PHOTOSYSTEM Ⅱ (PS Ⅱ) particles capable of O<sub>2</sub> evolution contain reaction center polypeptides D1 and D2, cytchrome b559, chlorophyll (Chl)-binding proteins CP47 and CP43, three extrinsic polypeptides (with apparent molecular masses of 17, 23 and 33 ku) and cofactors needed for light energy conversion. After illumination, PS Ⅱ oxygen evolution complex (OEC) catalyzes the oxidization of water to molecular oxygen through S<sub>0</sub>→S<sub>4</sub> redox state transition. The three extrinsic polypeptides have been revealed to be closely related to the photosynthetic O<sub>2</sub> evolution. 展开更多
