研究概要	生命一情報高速収集:1分子DNA配列直読法における要素技術(元素弁別電顕法、1本鎖DNAの延伸固定法、核酸塩基重元素ラベル法、特異的塩基対反応法、高速画像読取法)・膜蛋白質構造解析法における2次元結晶化法、蛋白質工学的電顕染色法における金属蛋白質の融合蛋白質発現手法等、の開発に着手した。電子顕微鏡用単結晶シリコン位相版のSOI基板に関して、SiとSiO2についての精密エッチング制御技術を確立し、極薄Si単結晶膜形成の準備を整えた。細胞系のin vivo生命情報:原索動物の胚発生における、局所Ca^<2+>濃度を制御する機能分子が集積する過程を解析し、Ca^<2+>イオンを正に制御する膜機能分子の発達が、負に制御する分子群の出現に先行することを見出した。また、細胞膜Ca^<2+>チャネル、細胞内膜Ca^<2+>放出チャネル、K^+チャネルの3者の空間的配置とCa^<2+>感受性による連携は、個体の運動の周波数である約15Hzの膜電位振動を生じることを明らかにした。細胞膜受容体活性化チャネルTRP1はストア依存性Ca^<2+>流入だけでなく、小胞体からのIP_3依存的Ca^<2+>放出をも制御することを示した。更には、細胞redox状態を感受し活性化して細胞死を仲介する、新規Ca^<2+>チャネルLTRPC2を同定した。生体シュミレーション:金属貯蔵蛋白質や膜チャネル蛋白質の機能メカニズムなど生理機能の調節機構を定量的に解明するため、鉄貯蔵蛋白質フェリチンフェリチン分子に関して、イオンの位置やアミノ酸残基置換の影響の実験データを、計算によって再現することができた。ナノバイオテクノロジーにおける応用:人工酵素による物質変換のシステム構築を目指し、シトクロームP450の機能を発現するヘム酵素の設計を行い、酸化活性種を与えるミオグロビンミュータントの反応サイトへ基質(トリプトファン)の導入を行い、ほぼ化学量論的に芳香環の水酸化反応を達成した。シリコンウエハー上の蛋白質集積パタン形成と新規バイオエレクトロニクス機能の研究においては、放射光ナノリソグラフィー専用のビームラインを建設し表面の平坦度Ra=0.33nmの超選択エッチングを確認した、また、Si(100)表面についてほぼ完全な水素終端表面を形成する、更に、その各種アルキル化合物との反応により、表面の親水性・疎水性を制御した自己組織単分子膜を形成する条件を見出した。
