| Research Abstract |
1. Color-tuning mechanism in Human red (HR), green (HG), and blue (HB) visual pigments was theoretically clarified in amino-acid level. The difference in absorption spectra between HR and HG could be explained in terms of direction of three hydroxyl residues in HR. 2. Mechanisms of color tuning in the M state of bacteriorhodopsin and in xanthorhodopsin were also investigated, which were compared with those in human visual pigments. 3. To analyze the mechanisms, new theoretical methods were developed.
