Outline of Final Research Achievements |
Type 1 Reaction Center (RC) is the simplest structures among 4 kinds of RCs. Phototrophs are classified into two groups, oxygenic phototrophs and anaerobic phototrophs, and they have each RC. The structural and functional relationships in type 1 RCs remain poorly understood because of the difficulty with sample preparations due to their highly fragile properties against oxygenic air. I resolved the crystal structure of Type 1 RC at 3.2 Å resolution and found one new peptide which function is unknown. The existence of quinone molecules in Type 1 RC was unknown for long time. I identified RC contains 0.8 molecule quinones and found the electron density of quinones in the crystal structure.
