| Outline of Final Research Achievements |
I developed a cryogenic microscope with a high spatial resolution. Using the developed system, I studied the dynamic movements of the antenna proteins, LHCII, during the state transition, which is a typical light-adaptation function of a green alga, chlamydomonas.
I conducted the single-molecule fluorescence spectroscopy for a photosynthetic protein, photosystem I (PS I). I observed for the first time the blinking of fluorescence from single PS I at around 90 K. I considered the imprecation of this observation for the conformation fluctuation of PS I.
I succeeded in reproducing the temperature dependence of the time-resolved fluorescence spectra of photosystem II using a microscopic model calculation based on the structure.
