Outline of Final Research Achievements

To elucidate the regulation mechanism of gene expression of light-harvesting proteins by a microbial rhodopsin ASR derived from cyanobacteria, we studied the sample preparation method and performed interaction between ASR and ASR transducer (ASRT).
We optimized the sample preparation method of ASR and ASRT, respectively. By isothermal titration calorimetry, flash photolysis and NMR using those samples, we investigated interaction between ASR and ASRT and succeeded in observing the interaction between ASR and ASRT in nanodisc system.
