Outline of Research at the Start

機能性蛋白質の動作機構のより深い理解には、揺らぎをもつ構造とその分布の理解が必須である。従来の溶液NMR法、結晶回折法などの解析法はそれぞれ溶液中の運動平均構造、結晶格子中での最安定構造を決める手法であり、動的平衡にある構造群全体の解析は難しかった。本研究では、動的核偏極(DNP)による超高感度固体NMRスペクトルの計算科学的な解析から、蛋白質の動的平衡構造を明示的に解析する新手法を開発する。

Outline of Final Research Achievements

Understanding dynamical structure distribution is essential for understanding the mechanism of protein function. The aim of this study was to develop a new method to analyze the structural distribution of membrane proteins by combining DNP-solid-state NMR and computational methods.
The plan was (i) sample preparation, (ii) development of a highly sensitive DNP-NMR methods, (iii) development of computational methodology, and (iv) application to membrane proteins, and in the three years through FY2022, (i)-(iii) were performed, samples were established, the DNP method was optimized, then the computational methodology was applied to model systems, which was published. From FY2023, we will restructure the project to a new plan including structural analysis of intracellular crowding environment in application to GPCR, and start as a new plan.

Academic Significance and Societal Importance of the Research Achievements

機能性蛋白質の動作機構のより深い理解には、揺らぎをもつ構造とその分布の理解が必須である。従来の溶液NMR法、結晶回折法などの解析法はそれぞれ溶液中の運動平均構造、結晶格子中での最安定構造を決める手法であり、動的平衡にある構造群全体の解析は難しかった。本研究で開発した方法は、動的核偏極(DNP)による超高感度固体NMRスペクトルの計算科学的な解析から、蛋白質の動的平衡構造を明示的に解析する新手法で、これまで解析が難しかった構造アンサンブルと蛋白質機能の解明を可能にする基盤技術である。
