Outline of Final Research Achievements

We studied the initial nuclear dynamics in a bacterial photoreceptor protein by ultrafast time-domain Raman spectroscopy. Newly developed high-order nonlinear Raman scheme enabled us to observe a distinct anharmonic coupling between the chromophore vibration and the hydrogen-bond motion surrounding the chromophore. The obtained result revealed the molecular mechanism of signal transduction in the primary photoreception process.

Academic Significance and Societal Importance of the Research Achievements

生体の中で起こる現象を分子レベルで観測することは、生命活動に対する深い理解につながる。このような観点から本研究では、光受容タンパク質の中の様々な部位の原子の動きを観測し、それらの動きどうしの相関を可視化することのできる新たな実験手法の開発に成功した。この成果は今後、生体内での連動した原子・分子の動きがいかにして生体信号を伝え、生命機能を発現および維持させているかという根源的な問いを解明していく手がかりのひとつになると考えられる。
