Abstract Photosynthesis reaction of water oxidized to oxygen is underwent by the catalyst of Mn-containing metal protein enzyme (oxygen evolving complexes). Its structure and mechanism are being understood more deeply as the biologists and chemists do more research on such enzymes. This paper gives a brief discussion about the High-valent oxomanganese clusters relevant to Oxygen-evolving Center in Photosystem II.

摘要 水氧化为分子氧的光合成反应是在含锰的金属蛋白酶(称作氧释放配合物)的催化下完成的。 随着生物学家和化学家对这种酶的深入研究，其结构和作用机理正在逐步揭开。本文就光系统Ⅱ中的释氧活性中心和高价氧锰簇配合物的研究作一简介。
