近年、硝酸イオンによる地下水汚染が問題となっており、硝酸イオン除去法の開発発展が求められている。電極触媒を用いた先行研究ではSnを修飾したPtやPdが高い触媒活性を示すことが報告されてきたが、その多くは多結晶電極を用いているため表面原子配列が活性に与える影響については明確にされていない。本研究ではPtやPd、Pd-Pt合金の単結晶電極を用いて、表面原子配列がその活性に与える影響について検討する。 , The Surface Science Society of Japan, Japanese - 多核銅錯体をカーボンに組み込んだ非白金系電極触媒

膜タンパク質は細胞膜を構成する脂質分子や他の可溶性タンパク質等と相互作用や電子移動することで,細胞膜を介したシグナル伝達やエネルギー生産といったタンパク質機能を発現することが知られている.膜タンパク質-脂質間やタンパク質-タンパク質間相互作用といった比較的弱い相互作用を膜タンパク質が機能している状態で直接観察することができれば,生体内反応の理解,医薬品やバイオセンサー開発等の促進が期待できる.
本研究では,膜タンパク質-脂質間やタンパク質-タンパク質間相互作用と酵素活性相関の理解を可能とする,人工生体膜固定化電極の構築を目指す.特に膜タンパク質の中でも生体内電子移動や酵素反応において重要であるヘムを含む膜貫通型金属酵素に着目する.2021年度では,ミトコンドリア内部で酸素を水へ還元する金属酵素であるチトクロムc酸化酵素の固定化電極を作製し,タンパク質の電極表面配向やリン脂質の種類の違いによる膜タンパク質-脂質間やタンパク質-タンパク質間相互作用,酵素活性への影響を調べた.酵素活性は電気化学測定により,人工脂質二分子膜形成やタンパク質間相互作用は表面敏感な分光手法である表面増強赤外吸収(SEIRA)分光測定により調べた.

In this work, we prepared gold electrodes that are active to surface-enhanced infrared absorption (SEIRA) spectroscopy and immobilized a nitric oxide reductase (NOR), which is a trans-membrane metalloenzyme and selectively catalyzes the reduction of nitric oxide (NO) to nitrous oxide (N2O). The NOR electrode showed the electro-catalytic NO reduction activity, indicating that the enzyme was active even on the gold electrode. We also performed SEIRA spectroscopy of the NOR electrode under potential control using carbon monoxide as a vibrational probe. Potential-dependent SEIRA spectra allowed us to determine the redox potentials of the heme and non-heme iron cofactors, which serve as the active site, and then gained the mechanistic insights into the enzymatic NO reduction.

ベンゾトリアゾール(Hbt)は配位可能な窒素原子を二つ有する両座配位子である.過去に酸化還元誘起結合異性を示すルテニウム錯体が合成されていて,Ru^の状態ではHbtが2位の窒素(N(2))で中心金属イオンに配位しているが,中心金属イオンを酸化してRu^ の状態にするとHbtが3位の窒素(N(3))で配位することが知られている.そこで,Hbtを両座配位子とし,補助配位子として光受容性配位子である2,2':6',2''-terpyridine (tpy)や2,2'-bipyridine誘導体を有するルテニウム錯体[Ru^ (Hbt) L (tpy)](CF_3SO_3)_2(Lは4,4'位をH,Me,OMe,tBu,Phで置換された2,2'-bipyridine誘導体)を合成し,溶液内酸化還元挙動をサイクリックボルタンメトリー測定により検討を行った.しかしながら酸化還元誘起結合異性に由来するようなピークを観測することはできず酸化還元誘起結合異性挙動が見られなかった.そこで,代替化合物として過去に我々が報告している酸化還元誘起結合異性を示す錯体[Ru(NH_3)_5(mi-S)]^ (mi=2-methylisothiazol-3(2H)-One ; n=3 or 2),光増感剤ルテニウム錯体[Ru^ (bpy)_3]Cl_2,そしてmethylviologen (MV)を用い,三元系分子間光電子移動反応による酸化還元結合異性を誘起するシステムの構築を目指した.その過程でRu^ の状態miが硫黄で,Ru^ では酸素で配位した錯体をそれぞれ合成単離し,単結晶X線構造解析によって構造を決定した。このように酸化還元結合異性体の単離例は極めて少なく,これは予期せぬ大きな成果であった.
