Outline of Final Research Achievements

Nuclear magnetic resonance (NMR) is a useful method for structural and functional analysis of proteins. A signal assignment process is a major bottleneck for analysis of difficult targets such as large proteins. In this project, based on our previously reported amino-acid selective isotope labeling method, SiCode (Stable isotope encoding), I developed (1) a signal assignment method using known three-dimensional structures, (2) a signal assignment method using two sets of SiCode samples, and (3) some methods helpful for analysis of difficult target proteins.

Academic Significance and Societal Importance of the Research Achievements

生命の様々な機能にとって重要な役割をもつタンパク質を解析することは、生命を理解しようとする基礎科学から、創薬などの応用まで、幅広い研究分野にとって重要である。本研究は、従来はNMR法による解析が困難であったり、不可能であったりしたタンパク質についても、迅速・簡便にシグナル帰属がおこなえる方法を提供することで、スピードアップをしたり、あるいは可能にしたりすることを目指すものである。
