Outline of Research at the Start

私たちの体の中では多くの分子が働いており、エネルギー変換、物質輸送、物質代謝などの生命活動を担っています。それらの生体分子は、形を巧みに変えながら働く、謂わば、小さな分子機械です。最近、生体分子が働く様子を動画として観測できる「時間分解Ｘ線構造解析」という手法が開発されました。私たちは、紫外光、可視光、赤外光などさまざまな光を道具に、時間分解Ｘ線構造解析では原理的に観測が難しい、電子レベルの細かな解析を精密に行ないます。時間分解Ｘ線構造解析と相補的に研究を進めながら、生体分子が働くしくみを物理化学的に解明します。

Outline of Annual Research Achievements

本新学術領域の目標の一つは、時間分解結晶構造解析（分子動画）を軸としたタンパク質のダイナミクス研究を他分野と複合的に融合させて、タンパク質を設計・制御・操作する新しい学問領域を形成することである。そこで本研究では、分子動画と時間分解分光法（紫外可視吸収分光、ラマン・赤外分光、蛍光分光）との相関的・補完的解析を推進し、分子動画と他手法との融合の先鞭をつける。
本研究では溶液測定に加えて、タンパク質微結晶を測定できる顕微測定技術を開発し、分子動画との相補解析を強く推進することを課題としてきたが、これまでに上記すべての分光法について顕微技術開発を完了している。これまでに、新規ロドプシン、ヘム酵素、DNAフォトリアーゼ、発光タンパク質等、分子動画研究の対象試料の分光計測を行い、昨年度までに成果をあげてきた。
本年度は、DNAフォトリアーゼの反応機構をさらに深く研究し、動物と植物とでDNA修復の光子数依存性に違いがあることを見出した。また、耐熱性ロドプシンについて、アスパラギン酸残基やグルタミン酸残基を介したプロトン輸送を時間分解赤外計測により明らかにした。また、ナトリウムポンプとしてはたらくKR2について、レチナールとの共有結合の重要性を明らかするほか、脱水時の可視吸収変化の分子機構もラマン分光等により明らかにした。その他、領域内共同研究として、温度ジャンプ分子動画計測や光化学系II中間体の分子動画計測の技術協力をした。
