| Research Abstract |
In the membrane of Halobaterium salinarum, there exists sensory rhodopsin (SR) which acts as a photoreceptor of phototaxis of this bacterium. Photo-induced proton transfer of SR was made clear. So-called M-intermediate is considered to be functionally important, but we showed that this intermediate is fragile. We devised the apparatus which can monitor time-resolved photo-induced proton transfer. We first showed a so-called N-intermediate in SR. The photochemistry of SRIII was first clarified.
