English, Scientific journal, Lactacystin is an irreversible proteasome inhibitor isolated from Streptomyces lactacystinicus. Despite its importance for its biological activity, the biosynthesis of lactacystin remains unknown. In this study, we identified the lactacystin biosynthetic gene cluster by gene disruption and heterologous expression experiments. We also examined the functions of the genes encoding a PKS/NRPS hybrid protein (LctA), NRPS (LctB), ketosynthase-like cyclase (LctC), cytochrome P450 (LctD), MbtH-like protein (LctE), and formyltransferase (LctF) by in vivo and in vitro experiments. In particular, we demonstrated that LctF directly transferred the formyl group of 10-N-formyl tetrahydrofolate to CoA. The formyl group of formyl-CoA was then transferred to ACP1 by LctA_AT1 to form formyl-ACP1. This is the first example of an AT domain recognizing a formyl group. The formyl group is perhaps transferred to methylmalonate tethered on LctA_ACP2 to yield methylmalonyl-semialdehyde-ACP2. Then, it would be condensed with leucine bound to PCP in LctB by the C domain in LctA. Using a mimic compound, we confirmed that LctC catalyzed the formation of the cyclic α,α-disubstituted amino acid structure with concomitant release of the product from PCP. Thus, we figured out the overall biosynthesis of lactacystin including a novel role of a formyl group in a secondary metabolite. - Optimization of tyrosol-producing pathway with tyrosine decarboxylase and tyramine oxidase in high-tyrosine-producing Escherichia coli

The Journal of antibiotics, 10 Jan. 2024, [International Magazine]
English, Scientific journal, Peptidoglycan is an important macromolecule in bacterial cell walls to maintain cell integrity, and its biosynthetic pathway has been well studied. Recently, we demonstrated that some bacteria such as Xanthomonas oryzae, a pathogen causing bacterial blight of rice, used an alternative pathway for peptidoglycan biosynthesis. In this pathway, MurD2, a MurD homolog, catalyzed the attachment of L-Glu to UDP-MurNAc-L-Ala and MurL, which did not show homology to any known protein, catalyzed epimerization of the terminal L-Glu of the MurD2 product to generate UDP-MurNAc-L-Ala-D-Glu. Because the alternative pathway also operates in some other plant pathogens and opportunistic pathogens, specific inhibitors of the alternative pathway could function as pesticides and antibiotics for these pathogens. In this study, we searched for specific inhibitors of the alternative pathway from metabolites produced by actinomycetes and identified a new oligomycin-class polyketide, which was revealed to inhibit the MurD2 reaction, in culture broth of Micromonospora sp. K18-0097. - Peptide Epimerase Responsible for

Nature Communications, 14, 1, Springer Science and Business Media LLC, 08 Aug. 2023
Scientific journal, Abstract
The lasso peptide MS-271 is a ribosomally synthesized and post-translationally modified peptide (RiPP) consisting of 21 amino acids with D-tryptophan at the C-terminus, and is derived from the precursor peptide MslA. MslH, encoded in the MS-271 biosynthetic gene cluster (msl), catalyzes the epimerization at the Cα center of the MslA C-terminal Trp21, leading to epi-MslA. The detailed catalytic process, including the catalytic site and cofactors, has remained enigmatic. Herein, based on X-ray crystallographic studies in association with MslA core peptide analogues, we show that MslH is a metallo-dependent peptide epimerase with a calcineurin-like fold. The crystal structure analysis, followed by site-directed mutagenesis, docking simulation, and ICP-MS studies demonstrate that MslH employs acid/base chemistry to facilitate the reversible epimerization of the C-terminal Trp21 of MslA, by utilizing two pairs of His/Asp catalytic residues that are electrostatically tethered to a six-coordination motif with a Ca(II) ion via water molecules. - Peptide epimerase-dehydratase complex responsible for biosynthesis of the linaridin class ribosomal peptides.

English, Scientific journal, Grisemycin, salinipeptin, and cypemycin belong to the linaridin class of ribosomally synthesized and posttranslationally modified peptides that contain multiple dehydrobutyrine and D-amino acid residues. The biosynthetic gene clusters of these linaridins lack obvious candidate genes for the dehydratase and epimerase required to introduce dehydrobutyrine and D-amino acid residues, respectively. However, we previously demonstrated that the grisemycin (grm) cluster contained cryptic dehydratase and epimerase genes by heterologous expression of this biosynthetic gene cluster in Streptomyces lividans and proposed that two genes (grmH and grmL) with unknown functions catalyze dehydration and epimerization reactions. In this study, we confirmed that both GrmH and GrmL, which were shown to constitute a protein complex by a co-purification experiment, were required to catalyze the dehydration, epimerization, and proteolytic cleavage of a precursor peptide GrmA by in vivo experiments. Furthermore, we demonstrated that GrmH/GrmL complex accepted salinipeptin and cypemycin precursor peptides, which possess three additional amino acids. - Studies on biosynthetic enzymes leading to structural and functional diversity of microbial natural products

Scientific journal, ABSTRACT
The primary metabolic pathways, for the most part, have been disclosed in Escherichia coli and Saccharomyces cerevisiae. These pathways were believed to be common among all microorganisms. However, after discovery of an alternative pathway for biosynthesis of isopentenyl diphosphate, the methylerythritol phosphate pathway, genome mining of alternative biosynthetic pathways for primary metabolites has been performed. My collaborators and I focused on the biosynthetic pathways of menaquinone and peptidoglycan because some microorganisms lack ortholog genes of the known biosynthetic pathways for these compounds. I also studied biosynthetic enzymes for secondary metabolites produced by actinomycetes and fungi because they include many unique enzymes. In this review, outlines of these studies are described. - N-Formimidoylation/-iminoacetylation modification in aminoglycosides requires FAD-dependent and ligand-protein NOS bridge dual chemistry.

English, Scientific journal, Oxidized cysteine residues are highly reactive and can form functional covalent conjugates, of which the allosteric redox switch formed by the lysine-cysteine NOS bridge is an example. Here, we report a noncanonical FAD-dependent enzyme Orf1 that adds a glycine-derived N-formimidoyl group to glycinothricin to form the antibiotic BD-12. X-ray crystallography was used to investigate this complex enzymatic process, which showed Orf1 has two substrate-binding sites that sit 13.5 Å apart unlike canonical FAD-dependent oxidoreductases. One site could accommodate glycine and the other glycinothricin or glycylthricin. Moreover, an intermediate-enzyme adduct with a NOS-covalent linkage was observed in the later site, where it acts as a two-scissile-bond linkage facilitating nucleophilic addition and cofactor-free decarboxylation. The chain length of nucleophilic acceptors vies with bond cleavage sites at either N-O or O-S accounting for N-formimidoylation or N-iminoacetylation. The resultant product is no longer sensitive to aminoglycoside-modifying enzymes, a strategy that antibiotic-producing species employ to counter drug resistance in competing species. - Ergothioneine production by Corynebacterium glutamicum harboring heterologous biosynthesis pathways.

English, Scientific journal, In this study, Corynebacterium glutamicum was engineered to produce ergothioneine, an amino acid derivative with high antioxidant activity. The ergothioneine biosynthesis genes, egtABCDE, from Mycolicibacterium smegmatis were introduced into wild-type and l-cysteine-producing strains of C. glutamicum to evaluate their ergothioneine production. In the l-cysteine-producing strain, ergothioneine production reached approximately 40 mg L-1 after 2 weeks, and the amount was higher than that in the wild-type strain. As C. glutamicum possesses an ortholog of M. smegmatis egtA, which encodes an enzyme responsible for γ-glutamyl-l-cysteine synthesis, the effect of introducing egtBCDE genes on ergothioneine production in the l-cysteine-producing strain was evaluated, revealing that a further increase to more than 70 mg L-1 was achieved. As EgtBs from Methylobacterium bacteria are reported to use l-cysteine as a sulfur donor in ergothioneine biosynthesis, egtB from Methylobacterium was expressed with M. smegmatis egtDE in the l-cysteine-producing strain. As a result, ergothioneine production was further improved to approximately 100 mg L-1. These results indicate that utilization of the l-cysteine-producing strain and introduction of heterologous biosynthesis pathways from M. smegmatis and Methylobacterium bacteria are effective for improved ergothioneine production by C. glutamicum. - First direct evidence for direct cell-membrane penetrations of polycationic homopoly(amino acid)s produced by bacteria

Scientific journal, Abstract
Bacteria produce polycationic homopoly(amino acid)s, which are characterized by isopeptide backbones. Although the biological significance of polycationic homopoly(amino acid)s remains unclear, increasing attention has recently been focused on their potential use to achieve cellular internalization. Here, for the first time, we provide direct evidence that two representative bacterial polycationic isopeptides, ε-poly-l-α-lysine (ε-PαL) and ε-oligo-l-β-lysine (ε-OβL), were internalized into mammalian cells by direct cell-membrane penetration and then diffused throughout the cytosol. In this study, we used clickable ε-PαL and ε-OβL derivatives carrying a C-terminal azide group, which were enzymatically produced and then conjugated with a fluorescent dye to analyze subcellular localization. Interestingly, fluorescent proteins conjugated with the clickable ε-PαL or ε-OβL were also internalized into cells and diffused throughout the cytosol. Notably, a Cre recombinase conjugate with ε-PαL entered cells and mediated the Cre/loxP recombination, and ε-PαL was found to deliver a full-length IgG antibody to the cytosol and nucleus. - Biosynthetic Gene Cluster of Linaridin Peptides Contains Epimerase Gene

English, Scientific journal,Abstract
Peptidoglycan in bacterial cell walls is a biopolymer consisting of sugars and amino acids and plays important role in maintaining cell integrity from the environment. Its biosynthesis is a major target for antibiotics and the genes and enzymes involved in the biosynthetic pathway have been well studied. However, we recently identified an alternative pathway in the early stage of peptidoglycan biosynthesis in Xanthomonas oryzae, a plant pathogen causing bacterial blight disease of rice. The distribution of the alternative pathway is limited to relatively few bacterial genera that contain many pathogenic species, including Xylella and Stenotrophomonas, besides Xanthomonas. Thus, the alternative pathway is an attractive target for the development of narrow-spectrum antibiotics specific to pathogens. In this minireview, we summarize the discovery of the alternative pathway and identification of its specific inhibitors. - Flavonoids from Woodfordia fruticosa as potential SmltD inhibitors in the alternative biosynthetic pathway of peptidoglycan

English, Scientific journal, SmltD is an ATP-dependent ligase that catalyzes the condensation of UDP-MurNAc-L-Ala and L-Glu to form UDP-MurNAc-L-Ala-L-Glu, in the newly discovered peptidoglycan biosynthesis pathway of a Gram-negative multiple-drug-resistant pathogen, Stenotrophomonas maltophilia. Phytochemical investigation of the 70% ethanol extract from Woodfordia fruticosa flowers collected in Myanmar led to the identification of anti-SmltD active flavonoids, kaempferol 3-O-(6''-galloyl)-β-D-glucopyranoside (1), astragalin (2), and juglalin (3). Among them, 1 showed the most potent SmltD inhibitory activity. An enzyme steady-state kinetic study revealed that 1 exerted competitive inhibition with respect to ATP. The results of this study provided an attractive foundation for the further development of novel inhibitors of SmltD. - Identification of the peptide epimerase MslH responsible for d-amino acid introduction at the C-terminus of ribosomal peptides

English, Scientific journal, We previously constructed a heterologous production system for ergothioneine (ERG) in Escherichia coli using five ERG biosynthesis genes (egtABCDE) from Mycobacterium smegmatis. However, significant amounts of hercynine (HER), an intermediate of ERG, as ERG were accumulated, suggesting that the reaction of EgtB catalyzing the attachment of γ-glutamylcysteine (γGC) to HER to yield hercynyl-γ-glutamylcysteine sulfoxide was a bottleneck. In this study, we searched for other EgtBs and found many egtB orthologs in diverse microorganisms. Among these, Methylobacterium strains possessed EgtBs that catalyze the direct conversion of HER into hercynylcysteine sulfoxide with l-cysteine (l-Cys) as a sulfur donor, in a manner similar to those of acidobacterial CthEgtB and fungal Egt1. An in vitro study with recombinant EgtBs from Methylobacterium brachiatum and Methylobacterium pseudosasicola clearly showed that both enzymes accepted l-Cys but not γGC. We reconstituted the ERG production system in E. coli with egtB from M. pseudosasicola; ERG productivity reached 657 mg L-1. - Recent advances in functional analysis of polyunsaturated fatty acid synthases.

English, Scientific journal, Polyunsaturated fatty acids (PUFAs) such as docosahexaenoic acid, eicosapentaenoic acid, and arachidonic acid are essential fatty acids for humans. PUFAs are biosynthesized by either desaturases/elongases from oleic acid or PUFA synthases from acetyl units. PUFA synthases are composed of three or four subunits, and each creates a specific PUFA even though the multiple catalytic domains in each subunit are very similar. We recently dissected these PUFA synthases by in vivo and in vitro experiments and elucidated how the enzymes control PUFA profiles. Moreover, for the first time, we converted a practical microalgal docosahexaenoic acid synthase into an eicosapentaenoic acid synthase based on the results. - Off-Loading Mechanism of Products in Polyunsaturated Fatty Acid Synthases.

English, Scientific journal, Marine microorganisms de novo biosynthesize polyunsaturated fatty acids such as docosahexaenoic acid and eicosapentaenoic acid by polyunsaturated fatty acid (PUFA) synthases composed of three or four polypeptides in a manner similar to fatty acid synthases (FASs). FASs usually possess thioesterase (TE) domains to release free fatty acids from acyl carrier protein (ACP)-tethered intermediates. Here, we investigated the off-loading mechanism with microalgal and bacterial PUFA synthases through in vivo and in vitro experiments. The in vitro experiments with acyltransferase (AT)-like domains and acyl-ACP substrates clearly demonstrated that the AT-like domains catalyzed the hydrolysis of acyl-ACPs to yield free fatty acids. - Subtle Control of Carbon Chain Length in Polyunsaturated Fatty Acid Synthases.

Japanese, Both fusicoccin A (FC) and structurally related cotylenin A (CN) are diterpene glucosides and show a phytohormone-like activity. However, only CN induces the differentiation of human myeloid leukemia cells. Since the CN producer lost its ability to proliferate during preservation, a study on the relationship between structure and activity was carried out and an elimination of hydroxyl group at 12-position of FC was essential to have the CN-like activity. Moreover, modified FC with hydroxyl group at 3-position was recently shown to be more effective. Therefore, we tried to identify a gene catalyzing 12-hydroxylation and to breed a mutant producing a modified FC without hydroxyl group at 12-position by a disruption of the gene. Previous identification of fusicocca-2,10(14)-diene synthase gene in Phomopsis amygdali, a FC producer, enabled us to identify a partial gene cluster for bisoynthesis of FC. However, other biosynthetic genes still remained unknown. In this study, we identified another gene cluster containing nine genes by draft genome sequencing. Of these, two cytochrome P450s catalyzing 813 and 9-hydrozylations, glycosylation, methylation, prenylation, and acetylation genes were confirmed to encode enzymes with the expected activities. We also identified a cytochrome P450 catalyzing 12-hydroxylations by a gene disruption experiment. The remaining one cytochrome P450 gene therefore probably catalyzes hydroxylation at the 19-position. - Synthesis of (+/-)-cyclic dehypoxanthine futalosine, the biosynthetic intermediate in an alternative biosynthetic pathway for menaquinones

Japanese, Isoprenoids are chemically diverse in nature, ubiquitous in living organisms, and crucial in biological processes. The biosynthesis of such isoprenoids proceeds through mevalonate and nonmevalonate pathways depending upon organisms and cellular organella, isopentenyl diphosphate (IPP) being a key intermediate in both cases. Metabolic engineering and control of these pathways should thus provide new opportunity to study intriguing chemistry and biochemistry involved and to develop selective chemotherapeutic agents and isoprenoid-related materials. We describe a new practical approach to the preparation of highly- and multiply deuterated isoprenoids, zeaxanthin and diterpene anitibiotic terpentecin being as examples, and its potential for analyzing the biosynthetic mechanism of isoprenoids, based on the metabolic engineering of microorganisms. Obviously, deuterium-labeled compounds are invaluable in biochemical, bioorganic as well as physicochemical research. Metabolically engineered E. coli DK223 (pTMV20, pACCAR25ΔcrtX) produces zeaxanthin under the presence of mevalonate. Fully deuterated mevalonolactone-d_9 (MVL-d_9), which had been synthesized, was supplemented to the culture of the above triply-engineered E. coli, and the biosynthesized zeaxanthin was extracted and purified by repeated chromatography. All the zeaxanthin formed was proved to be derived only from the supplemented MVL-d_9. This was the first example of such highly and multiply deuterated zeaxanthin, and clearly demonstrated significant potential of the present approach for the preparation of various isotope-labeled isoprenoids. Additional example of this approach was also demonstrated in the mechanistic study of cyclization reaction in the biosynthesis of diterpene anitibiotic terpentecin. Straightforward stereochemical analysis of isoprenoid biosynthesis was demonstrated by one-shot labeling of MVL-d_9 and ^1H NMR spectroscopy. Precise analysis of the simplified proton spectra of highly deuterated isoprenoids, especially under the deuterium decoupled conditions, appeared to be beneficial for mechanistic enzymology, particularly, for the key transformation involving proton attack and proton quench as observed in the terpene cyclase reactions. - Gene cloning and overproduction of low-specificity D-threonine aldolase from Alcaligenes xylosoxidans and its application for production of a key intermediate for parkinsonism drug

Pheganomycin (PGM) consists of the nonproteinogenic amino acid (S)-2-(3,5-dihydroxy-4-methoxyphenyl)-2-guanidinoacetic acid (1) at the N-terminus and a proteinogenic core peptide derived from NVKDGPT or NVKDR. The biosynthetic gene cluster responsible for the catalysis was identified in Streptomyces cirratus, containing a gene encoding a precursor peptide, including both core peptides, and several genes plausibly encoding enzymes for 1 biosynthesis and tailoring reactions. We searched for the gene responsible for the peptide bond formation between 1 and the peptides in the cluster, and identified pgm1, which has an ATP-grasp domain. A pgm1-deletion mutant lost PGM productivity, and recombinant PGM1 catalyzed the ATP-dependent peptide bond formation. This is the first example of cooperative peptide synthesis achieved by ribosomes and peptide ligases using a peptide as a nucleophile. PGM1 accepted a variety of peptides as the nucleophile and its flexibility was comprehended by the crystal structure of PGM1 and mutagenesis analyses.

Fungi produce diterpenes exhibiting phytohormone-related activities, such as gibberellin and fusicoccin. We identified a diterpene synthase gene PaFS, which is responsible for fusicoccin biosynthesis, in the mycelium of fusicoccin-producing fungus Phomopsis amygdali (Toyomasu et al., PNAS, 104: 3084-3088, 2007). PaFS (719 amino acids) possesses the diterpene cyclase domain at N-terminus and prenyltransferase domain at C-terminus. Our database search suggested that PaFS homologues exist in genome DNA of several fungal species. Among them, we found two PaFS homologous genes in Aspergillus oryzae genome database. It has been believed that A. oryzae produces few secondary metabolites including terpenoids. In this study, we characterize the two homologues, A. oryzae diterpene synthase like 1(AoDSL1) and AoDSL2. AoDSL1 contained a stop codon in region encoding prenyltransferase domain probably because of naturally occurred nonsense mutation, and is perhaps expressed as a truncated enzyme composed of N-terminal 412 amino acid residues. AoDSL2 encoded 728 amino acid residues, in which a successive Asp of DDxxD motif in the prenyltransferase domain was substituted by AN (position 482-483). These possible naturally occurred mutations perhaps resulted in loss of prenyltransferase activities. Recombinant AoDSL1 converted GGDP into two unknown diterpene cyclic hydrocarbons. The effects of site directed mutagenesis of possible naturally occurred mutation on enzyme activity will be presented., The Japanese Society for Chemical Regulation of Plants, Japanese - 微生物に見出されたメナキノン新規生合成経路

Gibberellins, a phytohormone, are biosynthesized from geranylgeranyl diphosphate (GGDP) via ent-kaurene. In higher plants, entkaurene was formed from GGDP via ent-copalyl diphsphate (ent-CDP) by two distinct diterpene cyclases, ent-CDP synthase and ent-kaurene synthase. Rice (Oryza sativa L.) produces diterpene phytoalexins, such as oryzalexins, momilactones and phytocassanes, of which biosynthetic hydrocarbon intermediates are converted from GGDP by the similar manner as ent-kaurene synthesis. We have shown that rice has two ent-CDP synthase genes; OsCPSl is for gibberellin biosynthesis and OsCPS2/OsCyc2 is for oryzalexins A-F and phytocassanes A-E. Although ent-CDP synthases for gibberellin biosynthesis from other plant species were well characterized, we have known little about properties of rice ent-CDP synthase for phytoalexin biosynthesis.Here, we enzymatically characterized recombinant putative mature OsCPS2/OsCyc2 as well as OsCPS4/OsCycl, syn-CDP synthase for mimilactones A and B and oryzalexin S, and compared to OsCPS1. The optima of pH (around neutral), temperature (around 30 oC), and divalent ion (0.1 mM Mg^<2+>) on OsCPS2/OsCyc2 and OsCPS4/OsCyc1 were almost the same as OsCPS1. Interestingly, the inhibition rate of activities of OsCPS2/OsCyc2 and OsCPS4/OsCyc1 by substrate, GGDP (50-60μM), and Amo-1618 (10^<-5>-10^<-4>M), a gibberellin biosynthetic inhibitor which suppresses ent-CDP synthase activity, was less than that of OsCPS1., The Japanese Society for Chemical Regulation of Plants, Japanese - リベロマイシンA生合成遺伝子クラスターの解析

(1) MurL catalyzing the epimerization of the terminus L-Glu of UDP-MurNAc-L-Ala-L-Glu, an intermediate in the alternative biosynthetic pathway of peptidoglycan, was shown to activate the substrate by adenylation of α-carbonyl of the L-Glu. By crystal structure analysis, we were unable to determine the active amino acid residues of MurL, and co-crystal of MurL with a mimic of adenylated substrate was thought to be essential for estimation of the active residues and the reaction mechanism. (2) MslH catalyzed the epimerization of C-terminal L-Trp in a ribosomal peptide MS-271. By crystal structure analysis, active amino acid residues, divalent cation trapping residues, and several substrate recognition residues were identified. (3) Polyglutamate contains D-Glu besides L-Glu. PgsA, a polyglutamate biosynthetic enzyme, was suggested to be the epimerase catalyzing isomerization of terminal L-Glu that is just ligated to the elongating polyglutamate substrate.

In this project, we have made a dramatic development from simply learning biosynthetic machineries to designing new blueprints for producing desired natural products. Based on the detailed analyses of the structural diversity of natural products from the viewpoint of genes, enzymes, and reactions, we established a new world-leading technology platform for creation of complex functional molecules by rational reconstruction of biosynthetic machineries as a new academic field. In order to facilitate the research plan, the project team formulated a research policy and provided a forum to actively promote exchanges, collaborations, and joint research among individual research promoters. Researchers from various fields collaborated and complemented each other in their areas of expertise to conduct joint research and create a new academic field.

Polyunsaturated fatty acids (PUFAs) such as docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and arachidonic acid (ARA) are essential fatty acids for humans. PUFAs are biosynthesized by either desaturases/elongases from oleic acid or PUFA synthases from acetyl units. PUFA synthases are composed of three or four subunits and each creates a specific PUFA even though the multiple catalytic domains in each subunit are very similar. We dissected these PUFA synthases by in vivo and in vitro experiments and elucidated how the enzymes control PUFA profiles. Moreover, for the first time, we converted a DHA synthase into an EPA synthase by one amino acid substitution.

We recently discovered novel pseudotripeptides, ketomemicins, which possess a C-terminal pseudodipeptide connected with a carbonyl methylene instead of an amide bond. The carbonyl methylene structure is stable than amide bond and its biological significance has been shown in several natural and synthetic compounds. Despite the biological significances of these compounds, little is known about its biosynthetic machinery. We therefore examined it by in vitro studies with recombinant enzymes. Consequently, an aldolase, dehydratase, PLP-dependent glycine-C-acetyltransferase, and dehydrogenase were revealed to be involved in the formation of the pseudodipeptide with malonyl-CoA and phenylpyruvate as starter substrates.

Pheganomycin (PGM) (1) consists of a nonproteinogenic amino acid, (S)-2-(3,5-dihydroxy-4-methoxyphenyl)-2-guanidinoacetic acid (2) at the N-terminus and a proteinogenic core peptide derived from NVKDGPT or NVKDR. The biosynthetic gene cluster was identified in Streptomyces cirratus to contain a gene encoding a precursor peptide, which included both the core peptides, and several genes plausibly encoding enzymes for 2 biosynthesis. We identified a gene (pgm1) responsible for the peptide bond formation between 2 and the peptides in the cluster. A pgm1-disruptant lost 1 productivity and recombinant PGM1 catalyzed the ATP-dependent peptide bond formation. This is the first example of cooperative peptide synthesis achieved by ribosome and peptide ligase using a peptide as a nucleophile. PGM1 accepted a variety of peptides as the nucleophile and the flexibility was comprehended by the crystal structure of PGM1 and the mutagenesis analyses.

1. Fusicoccin A is a diterpene glucoside produced by the fungus Phomopsis amygdali and its derivative lacking the OH group at the 12-position is revealed to be a potential anti-cancer drug. We therefore constructed a mutant producing the desirable intermediate by biosynthetic engineering. 2. Three fungal prenyltransferases, PaxC, PaxD, and AtmD, all of which are responsible for biosynthesis of indole diterpene compounds, were characterized. 3. Aminodeoxyfutalosine is the first intermediate in the new menaquinone biosynthetic pathway. We demonstrated that a radical S-adenosyl methionine enzyme (MqnE) catalyzed the addition of the adenosyl radical to the double bond of 3-[ (1-carboxyvinyl)oxy]benzoic acid derived from chorismate by MqnA. 4. During the biosynthetic studies of pheganomycin, we identified a new ATP-grasp enzyme, which phosphorylated the non-proteogenic amino acids with ATP and the successive nucleophilic attack of the peptides.

Folate is an essential cofactor in all living cells. para-Aminobenzoate (pABA), a building block of folate, is usually derived from chorismate in the shikimate pathway by reactions of PabABC. We previously suggested that an alternative pathway for pABA biosynthesis would operate in some microorganisms such as Lactobacillus fermentum and Nitrosomonas europaea since these bacteria showed a prototrophic phenotype to pABA despite the fact that there are no orthologs of pabABC in their genome databases. In this study, a gene of unknown function, NE1434, was obtained from N. europaea by shotgun cloning using a pABA-auxotrophic Escherichia coli mutant (dpabABC) as a host. A tracer experiment using [U-13C6]glucose suggested that pABA was de novo synthesized in the transformant. An E. coli dpabABCdaroB mutant carrying the NE1434 gene exhibited a prototrophic phenotype to pABA, suggesting that compounds in the shikimate pathway including chorismate were not utilized as substrates by NE1434.

Glutathione; Streptomyces strains do not use glutathione. However, SCO0910 was confirmed to be glutamate-cysteine ligase and was essential for ergothioneine biosynthesis. Taurine; SCO3035 in S. coelicolor A3(2) was reported to be the first enzyme in taurine biosynthesis (J. Bacteriol. 188, 5561, 2006). To investigate taurine biosynthesis in S. coelicolor A3(2), SCO3416, 2782, and 2017, putative enzymes catalyzing thesecond reaction, were used for in vitro assay. However, all enzymes did not show the expected activity.

The futalosine pathway is operating in some bacteria for the biosynthesis of menaquinone. Futalosine is converted into dehypoxanthinyl futalosine (DHFL) by MqnB.In this study, three routes to the formation of DHFL were suggested. DHFL may have been directly formed by MqnB in Thermus thermophilus. In Streptomyces coelicolor, aminodeoxy FL (AFL) was converted to FL by deaminases, then to DHFL. In contrast, MqnB of Helicobacter pylori directly converted AFL into DHFL.
To identify compounds that specifically inhibit the futalosin pathway, we used B. halodurans that has FL pathway as a test strain. Finally, two candidate fungal culture broths were obtained.

メナキノン(ビタミンK)は、微生物にとって電子伝達系成分として生育に必須である。筆者は、Helicobacter属(ピロリ菌)、Campylobacter属、Wolinella属などの病原微生物や、放線菌Streptomyces属などの微生物では、今まで知られていた経路とは全く異なるフタロシン経路で生合成されることを見出した。今年度、本経路の2番目の反応を触媒するfutalosine hydrolase(MqnB、最近EC3.2.2.26が付与された)の諸性質を高度好熱菌Thermus thermophilusの組換え酵素を用いて検討した。その結果、以下の性質を示した。(1)Futalosineのみが基質となり他の核酸類縁体は基質にならないこと、(2)4量体を形成、(3)至的pHは4.5、(4)至的温度は80度、(5)Km値154.0±5.3μM、kcat1.02/s、(6)hypoxanthineにより弱く阻害されること(Ki値1.1mM)。本酵素がhypoxanthineにより弱く阻害されたことから、hypoxanthine誘導体を合成し、本酵素特異的阻害剤を探索することにより、抗ピロリ菌剤の開発が可能になると期待された。
また天然物からの抗ピロリ菌リード化合物の探索も行った。大学設備ではピロリ菌を培養できないため、2種類のBacillus属細菌を用いた系で一次スクリーニングを行った。同じBacillus属に属しながら、Bacillus haloduransがメナキノン生合成の際、新規経路を使うのに対し、Bacillus subtilisは既知経路を使う。そこで、(1)B.haloduransに対し抗菌作用を示すが、B.subtilisには影響を及ぼさない化合物を放線菌・カビの培養液中に探索した。次に、(2)B.haloduransに対する生育阻害が、外からメナキノンを添加した際、回復するか検討した。その結果、放線菌の培養中に1つの候補化合物を見出した。現在、本化合物の精製と構造解析を行っている。

ジテルペン化合物は(炭素数20)、香料、医薬・医薬中間体、植物ホルモンなど重要な化合物を含んでいる。これら化合物の生合成の第一段階は、環化酵素が直鎖状の基質であるゲラニルゲラニル2 リン酸の末端オレフィンをプロトン化、または2 リン酸を脱離することによってカルボカチオンを生成することから始まる。最終的にカルボカチオンが捕捉中性化されるまで、各環化酵素特有のカチオン中間体を経る反応が順次進行し、多種多様なイソプレノイド骨格へと導かれる。反応の第一段階が共通であるにもかかわらず、最終的に多様な骨格を持つ化合物が生成する事実は、環化酵素の特定アミノ酸残基のみが反応に関与するのではなく、酵素全体のアミノ酸残基が種々のカルボカチオン中間体の生成に関与することを示唆する。従って、これら環化酵素の構造機能相関解析を行うことにより、任意の段階でカルボカチオンが捕捉中性化された化合物の生成を制御できる可能性がある。しかし環化酵素に関しては、真核生物を材料に用いた場合、酵素調製が難しいことなどから一部の酵素を除いて殆ど解析が行われていない。このような背景下、筆者は原核生物と真核生物起源のイソプレノイド生合成遺伝子を多数取得しており、今回、(1)お米由来の2 つのent-copalyl diphosphate 生合成酵素、(2)原核生物のNocardia 属放線菌が生産するジテルペン化合物、brasilicardin A 生合成遺伝子クラスターの取得、(3)原核生物のStreptomyces 属放線菌により生産されるテトラテルペン化合物(KS-505a)生合成遺伝子クラスターの取得とこれらの機能解析を行った。

メナキノン(ビタミンK)は,人間にとっては血液凝固に必要なビタミンであり,また微生物では電子伝達系成分として生育に必須である。申請者は,胃潰瘍・胃がんの原因菌として知られているHelicobacter属細菌、食中毒原因菌として知られているCampylobacter属細菌,グラム陽性の土壌細菌であるStreptomyces属細菌などの微生物では,既知の生合成経路として知られているコリスミ酸からメナキノンに至る5ステップの生合成遺伝子群が全く存在しないことに気づいた。そこで,この新規経路の全容解明を行っている。
1.これまでにStreptomyces属放線菌を材料に用いて,バイオインフォマティクスにより絞り込んだ遺伝子を破壊することにより,7つの遺伝子群が新規経路に関与することを明らかにした(これらの成果については未発表のため,これら遺伝子群を以下men06,men26,men27,men50,men90,men92,men94と略号で記載する)。
2.また新規経路遺伝子の網羅的取得を目指し,変異剤によるメナキノン生合成欠損株の誘導と相補遺伝子の取得も行った結果,新規経路は既知経路同様コリスミ酸を出発基質とするが,その後全く別経路を経ることも分かった。
3.上述の破壊株を2つ組み合わせてメナキノン非存在下で混合培養を行った結果,幾つかの菌株の組み合わせで生育が認められた。本現象を利用し,破壊株が関与する生合成上の相対的な位置を(men06)→(men26,men27,men50)→(men90,men92,men94)→メナキノンのように明らかにすることができた。
4,上述したアッセイ系を用い,破壊株が蓄積する中間体の精製・構造決定を行い,3つの化合物の構造を決定した。

We found that some pathogenic bacteria including Helicobacter pylori and Campylobacter jejuniutilized a new biosynthetic pathway for menaquinone. This pathway is also present in the genus Streptomyces and branches from the well known menaquinone biosynthetic pathway at chorismate. Since this pathway does not present in human, its inhibitors are expected to be useful as antibacterial substances. In order to reveal the details of this pathway, we carried out the following experiments.
1. At the onset of the experiments, we established unequivocal assignment of 13C-N1VIR spectrum of menaquinone.
2. Labeling experiments using glucoses labeled by^<13>C at different position proved that menaquinone was formed from erythrose, phosphoenolpyruvate and two different C_2 units originating from C5-C6 of glucose.
3. Several kinds of blocked mutants of Streptomyces coelicolor that required menaquinone for their growth were prepared.
4. Based on the results obtained by labeling experiments, 1,4-naphthoquinone-6-carboxylic acid was assumed to be a biosynthetic intermediate of the new pathway. Therefore, we prepared this acid by oxidation of naphthalene-2-carboxylic acid by using Ce(SO_4)_2. This compound enabled the growth of a menaquinone auxotroph of S coelicolor indicating that the synthetic compound is a true intermediate of the new pathway.
5. By detailed investigation of metabolites accumulated by mutants of S coelicolor a nucleoside compound, futalosine, was isolated. This compound consisted of inosine and a m-substituted benzoic acid derivative, and had been isolated from another strain of Streptomyces as an antitumor substance. This compound was proved to be a biosynthetic intermediate of the new pathway, since it supported the growth of some menaquinone auxotrophs of S coelicolor.
6. By utilizing other menaquinone auxotrophs of S coelicolor, several intermediates after futalosine were identified.

A cDNA encoding fusicoccadiene synthase (PaFS) was isolated from mycelia of fusicoccin-producing fungi. PaFS possesses two domain, terpene cyclase domain at N-termini and prenyltransferase domain at C-termini, and shows multifunctional catalyzation. We have clarified the detailed cyclization mechanism forming fusicoccane skeleton from GGDP, and have succeeded in synthesizing a fucicoccin derivative that has a differentiation inducing activity. Mechanism on construction of molecular skeleton of diterpene, phomaction was investigated by chemical methods. Heterologous expression of the genes responsible for biosynthesis of diterpene, aphidicolin using yeast was explored. A common biosynthetic intermediate of indole diterpenoide was synthesized as non-and deuterium-labeled form. The deuterium-labeled intermediate was converted into paxilline and emindole DA via epoxidation and cyclization in two different fungi in an intact manner. These results give first evidence that various indole diterpenoide are biosynthesized from a common intermediate. We have cloned three diterpene cyclase genes and one tetraterpene cyclase gene from actinomycetes. Of the four cyclases, enzymatic properties of the two diterpene cyclases were investigated with recombinant enzymes. The functional analyses were performed in respect to Rv3377c and Rv3378c involved in Mycobacterium tuberculosis H37 strain. These genes encode diterpene synthases for producing halimane skeleton. Studies on squalene cyclase were also conducted to gain more insights into the catalytic mechanism. Successful site-specific incorporation of fluorophenylalanines into the catalytic sites demonstrated the importance of cation-pi interaction. In vitro translation system revealed the function of a diterpene cyclase gene from the moss Physcomoitrella patens. This system was also available for determination of production and localization of cytochrome P450 monooxygenase proteins. The function of P450 monooxygenases responsible for biosynthesis of plant hormones, brassinosteroid and gibberellin, was revealed by heterologous expression in Pichia pastoris. We identified 6 cDNAs encoding diterpene cyclases responsible for phytoalexin bisynthesis in rice. We indicated strong evidence for the presence on chromosome 4 of a gene cluster involved in momilactone biosynthesis. The presence of phytocassane biosynthesis gene cluster on chromosome 2 was also suggested.

We have cloned a DNA fragment that contained four ORFs and was confirmed to participate in viguiepinol {3-hydroxypimara-9(11),15-diene} biosynthesis by a heterologous expression experiment, from Streptomyces sp.strain KO-3988. Of the four ORFs, ORF2 and ORF4 were confirmed to encode an ent-copalyl diphosphate(CDP) synthase and a geranylgeranyl diphosphate(GGDP) synthase, respectively, by experiments using recombinant enzymes. ORF3,that did not show similarities with any other known proteins was also expressed in E.coli and used for functional analysis. The purified ORF3 product clearly converted ent-CDP into pimara-9(11),15-diene. Since ORF2 and ORF3 are the first examples of enzymes with these biosynthetic functions from prokaryotes, enzymatic properties of both enzymes were investigated. ORF2 is likely to be a dimer and requires a divalent cation such as Mg^<2+> and Zn^<2+> for its activity. The optimum pH and temperature were 5.5 and 35℃. The Km value was calculated to be 13.7±1.0μM for GGDP and the kcat value was 3.3 x 10^<-2>/sec. ORF3 is likely to be a monomer and also requires a divalent cation. The optimum pH and temperature were 7.0 and 30℃. The Km value for ent-CDP was estimated to be 2.6±0.2μM and the kcat value was 1.4 x 10^<-3>/sec.

Fubacterial diterpene cyclase genes have been doned from a diterpenoid-antibiotic, terpentecin producer. Their products, ORF11 and ORF12, were confirmed to be essential for the conversion of geranylgeranyl diphosphate (GGDP) into terpentetriene (TTE) that had the same -basic skeleton as terpentecm. Functional analyses of these two enzymes were also performed by using purified recombinant enzymes. The ORF11 product converted GGDP into a cydized intermediate (terpentedienol diphosphate, TDP), and then it was transformed into TTE by the ORF12 product. Interestingly, the ORF12 product directly reacted with GGDP and converted GGDP into three olefinic compounds. Moreover, the ORF12 product reacted even with farnesyl diphosphate (FDP) giving three olefinic compounds, which had the same structures as those formed from GGDP except for the chain-lengths. These results suggested that the ORF11 product with a DXDD motif converted GGDP into TDP by a protonation-initiated cyclization and that the ORF12 product with a DDXXD motif completed the reaction by an ionization-initiated reaction of substrates to an allylic carbocation followed by deprotonation to the olefin. Kinetics of the ORF12 product indicated that the affinity for TDP and GGDP were higher than that of FDP and that the relative activity of the reaction converting TDP into TTE. was highest among the reactions using TDP, GGDP, or FDP as the substrate. These results suggested that an actual reaction catalyzed by the ORF12 was the conversion of TDP into TTE in vivo.

(1)We isolated (+)-cyatha-3,12-diene from an erinacine-producing fungus, and confirmed its stereostructure by semi-synthesis from erinacine P. The cyathane hydrocarbon could be obtained from GGDP by the cell-free system. From a fusicoccin-mass-producing fungus we isolated (+)-δ-araneosene as the presumed bicyclic hydrocarbon intermediate. (+)-Fusicocca-3(16),10(14)-diene was also isolated and its identification suggested the presence of a new fusicoccenyl cation in the biosynthetic pathway. (2)We identified two gene clusters responsible for diterpene biosynthesis by chromosome waling from GGDP synthase genes from Phomopsis amygdali. The gene clusters led us to successful isolation and characterization of two cDNAs encoding diterpene cyclases. (3)The gene cluster for aphidicolin biosynthesis has been identified by PCR-based genome walking using reported sequence of cDNA coding the diterpene cyclase. Based on non-enzymatic cyclization under various conditions and molecular orbital calculations, cyclization mechanism for construction of aphidicolane skeleton was proposed. (4)We have cloned two diterpene cyclase genes essential for biosynthesis of terpentecin. By using recombinant enzymes, it was revealed that one enzyme converted GGDP into a cyclized intermediate (terpentedienol diphosphate), and then it was transformed into terpentetriene by the other enzyme. (5)By using the site-specific mutants and the substrate analogs, we clearly demonstrated that the steric bulk size of active site residues has an important role in determining the folding conformation of squalene substrate during the polycyclization cascade.

Two gene clusters containing the mevalonate pathway genes and the terpentecin (TP) biosynthetic genes were cloned from Streptomyces griseolosporeus strain MF730-N6, a diterpenoid antibiotic, TP producer. In the former cluster, seven genes enecoding geranylgerairyl diphosphate synthase (GGDPS), mevalonate kinase (MK), mevalonate diphosphate decarbosylase (MDPD), phosphomevalonate kinase (PMK), isopentenyl diphosphate (IPP) isomerase, HMG-CoA reductase, and HMG-CoA synthase were suggested to exist in that order. Heterologous expression of these genes in Ε. coli and Streptomyces Iividans, both of which have only the nonmevalonate pathways, suggested that the genes for the mevalonate paftway were involved in the cloned DNA fragment. The GGDPS, MK, MDPD, PMK, IPP isomerase, and HMG-CoA synthase were expressed in Ε. coli. Among them, the recombinant GGDPS, MK, and IPP isomerase were confirmed to have the expected activities. In the latter cluster, two ORFs, ORF11 and ORF12 that encode proteins showing similarities to eucaryotic diterpene cyclases (DCs) and a eubacterial pentalenene synthase, respectively, were found. The two cyclase genes were expressed in Streptomyces Iividans. The transformant produced a novel cyclic diterpenoid, ent-clerod-3,13(16),14-triene (terpentetriene), which has a common basic skeleton as does TP. The two enzymes were overproduced in Ε. coli and purified to homogeneity. The recombinant ORF11 product converted GGDP into an intermediate with diphosphate, and then it was transformed into terpenteteiene by the recombinant ORF12 product. To the best of our knowledge, this is the first report about a eubacterial DC.

Tautomycin (TM) isolated from a culture broth of Streptomyces spiroverticillatus is an inhibitor of protein phosphatases 1 and 2A. Since TM and its analogues are expected to be useful probes for elucidating the signal trasduction of mammalian cells, we studied on the absolute structure, conformational analysis, structure-activity relationship, and biosynthesis of the polyketide compound, TM. In the present study, we have studied on the cloning and analysis of TM biosynthetic genes. Here I report the results of experiments done in 1996, 1997 and 1998.
1. Development of transformation system: Protoplast formation and regeneration of the TM producer were achieved by using the reported procedure for other Streptomyces sp. In addition to above experiments, the transformation system was established by curing the producer of the cryptic plasmid by a heat shock treatment. The satisfactory efficiency of 2 x 10ィイD15ィエD1 transformants/μgDNA was obtained using the pIJ702 plasmid, with the result that we optimized various conditions of the transformation system.
2. Cloning of the putative TM biosynthetic gene: The KS and AT primers, which were designed from the published sequences in PKS Type I, were used in PCR strategy to obtain products. The primer design strategy was successful in identifying a fragment from S. spiroverticillatus genomic DNA and a PKS on cosmid pWE15. Sequence analysis of the PCR product strongly suggests that we have cloned a PKS gene flagment in the TM producer.
3. Gene disruption of the putative TM biosynthetic gene: To determine whether the PKS gene fragment obtained from PCR strategy indeed encodes PKS involving in TM biosynthesis, the fragments were then used for gene disruption by recombinational insertion of the cloned 1.8 kb region into the corresponding region on the chromosome. The resulting 15 strains were fermented and assayed for the presence of TM. Although none of the strains produced TM, an another antibiotic xanthostatin was produced by all strains. Genomic Southern hybridization analyses showed that TM biosynthetic genes in these strains were deleted from the genomic DNA.

(1) Phenylalanine dehydrogenase (PheDH) : PheDHs from Bacillus sphaericus, B.badius, Sporosarcina ureae were purified from Escherichia coli transformants in large scales and sent to Prof.Engel (University College Dublin, Ireland) and Prof.Rice (University of Sheffield, U.K.) for X-ray crystallography. Based on informations of X-ray crystallography of glutamate dehydrogenase, chimeric enzymes of PheDH with altered substrate specificities were constructed.
(2) Methylaspartate ammonia-lyase (MAL) : MALs from Enterobacteria such as Enterobacter, Citrobacter, Proteus were purified to homogeneities and their enxymological properties were analyzed in detail. MAL from Citrobacter amalonaticus strain YG-1002 was digested with endo peptidases and N-terminal amino acid sequences were determined. Based on the information, DNA probes were synthesized. The gene for the enzyme was cloned form the genomic library of c.amalonaticus strain YG-1002 by PCR and Southern hybridization. The sequence of the gene was compared with that of a strict anaerobe Clostridium tetanomorphum. MAL was crystallized and sent to Prof.Rice for studies of X-ray crystallography.
(3) Opine dehydrogenase (ODH) : The gene for ODH from Arthrobacter sp.IC was cloned and expressed in E.coli. The enzyme was purified in a large scale and sent to Prof.Rice, and on its X-ray studies were started. The first structure of a (D,L) superfamily member, N-(1-D-Carboxylethyl)-L-norvaline dehydrogenase from Arthrobacter sp.strain 1C,has been solved to 1.8* resolution and the location of the bound coenzyme determined.
(4) Results were presented in some international academic meetings.

First, we screened for microorganisms having new hydro-lyases catalyzing hydration of maleic acid and itaconic acid, respectively, to produce D-malic acid and citramalic acid which are food additives and starting materials in synthetic organic chemistry, etc. The bacterial maleate hydratase from Arthrobacter sp. was purified to homogeneity and characterized. The culture and reaction conditions for the production of optically pure D-malate from maleate were studied. Under an optimum condition, 87 grams/liter of D-malate was produced in 20 h. The yield was 72 mole %. (S)-(+)-Citramalate producing activity from itaconate was also studied. A.denitrificans produced (S)-(+)-Citramalate in a 99.9 % enantiomeric excess. Under an optimum condition, 27 g of (S)-(+)-citramalate per liter was produced in 30 h. The yield was 69 mol%.
Second, a screening was carried out for new 3-methylaspartate ammonia-lyases which catalyze the synthesis of L-aspartic acid derivatives from fumaric acid derivatives. We discovered for the first time that 3-methylaspartate ammonia-lyase (MAL) producers are relatively widely distributed in the family of facultatively anaerobic Enterobacteriaceae. Crystalline MALs from Citrobacter freundii, C.amalonaticus, and Morganella morganii, were characterized. Using cell-free extracts of the isolates, optically pure (2S, 3S)-3-methylaspartic, (2S, 3S)-3-ethylaspartic, and (2R, 3S)-3-chloroaspartic acids were synthesized from corresponding fumaric acid derivatives.
