摘要：

Effects of Photosystem II (PS II) extrinsic polypeptides of oxygen-evolving complex and manganese clusters on PS II carbonic anhydrase (CA) were studied with spinach PS II membranes. The result supported that membrane-bound CA is located in the donor side of PSII. The extrinsic polypeptides played an important role of maintaining CA activity. After removing manganese clusters, oxygen evolution activity was inhibited, but PSII-CA activity was unchanged. It was concluded that CA activity is independent of the presence of manganese clusters, and was not directly correlated with oxygen evolution activity.
