摘　　要：光合放氧是植物光系统II(PSII)的重要功能之一。PSII的放氧反应主要是由PSII氧化侧的 4个锰原子组成的锰簇催化的。在类囊体膜的囊腔侧还结合有若干个外周蛋白 ,对放氧反应起着重要作用。In green plants, oxygen evolution is one of the most important physiological function of photosystem II(PSII). A manganese cluster composed of four manganese atoms plays a crucial role in the oxygen evolution at the donor side of photosystem II. Meanwhile, several extrinsic proteins, binding at the lumen side of the membrane, are also necessary for efficient oxygen evolution by PSII. In this reiew, the progress in the research on the structure and function of extrinsic proteins, especially the 33 kD extrinsic protein, was presented. Table 1 includes relative structure information obtained from far UV CD, FTIR and secondary structure prediction on the 33 kD extrinsic protein in solution. Figure 1 shows a hypothetical model of the folding structure of the 33 kD extrinsic protein.
