Research Abstract

2-1. 忌避応答光センサー蛋白質、SRIIの機能発現分子メカニズム
現在阪大/水谷グループと共同で、機能・構造変化に必須のアミノ酸残基(Tyr174)の変化を検出するため、時間分解紫外共鳴ラマン測定を行っている。
2-2. デュアル光センサー蛋白質、SRIの機能発現メカニズム
(1)新しいSRI分子、SrSRIのCl^-依存的光反応変化を見出した[J.Mol.Biol. 2009](A01:藤井グループとの共同研究)。(2)新しいSRI分子、HvSRIの発現・精製と分光解析[Biochemistry 2010](A01:藤井グループとの共同研究)。(3)SrSRIと伝達タンパク質、SrHtrIの複合体の機能発現系構築に成功し、その分光学的解析を行った[Biochemistry 2009a](A01:藤井グループとの共同研究)。
2-3. SRI-HtrIが制御するべん毛蛋白質の解析
SRI-HtrIが受けた光情報は、最終的にべん毛モーターの回転方向の制御として出力される。ここでは、べん毛固定子タンパク質MotBの部分結晶構造と[Mol.Microbiol. 2009]、赤外分光法によるNa^+透過経路の検討を行った[Biochemistry 2009b]
このように光センサータンパク質の機能発現機構について、分子科学的に迫ることが出来た。
