Research Abstract |
Sensory rhodopsin II (SRII) is a photophobic receptor protein in halobacteria. In this study, we attempted to characterize a long-lived photoproduct (Mlike intermediate) that was formed in SRII from Halobacterium salinarum under continuous illumination and reveal the physiological role of it. Through the experiment using hydroxylamine, a water-soluble reagent, the hydrophilic environmental change in the protein interior at Mlike state was observed. In addition, the effects of the mutation of two amino acid residues (Asp103 and Ser201) located in the vicinity of the retinal on the phototaxis were investigated.
