摘要
光合水氧化是地球上最重要的生化过程之一。光合放氧生物包括光系统Ⅰ (PSⅠ )和光系统Ⅱ(PSⅡ )两种类型反应中心 ,光系统Ⅱ反应中心能以水作为电子给体 ,利用光能氧化水产生质子和氧气。对于水如何被氧化这个难题前人已做了大量的工作 ,但到目前为止放氧复合物 (OEC)的结构及水氧化的机理仍不清楚。本文结合当前研究结果 ,就光合放氧复合物的结构及光合放氧机理进行了综述 ,希望能有助于推进这方面的工作。
Photosynthetic water oxidation is one of the most important biochemical processes on Earth. Oxygen-evolving photosynthetic organisms contain two types of photosynthetic reaction center, called photosystem Ⅰ(PSⅠ) and photosystem Ⅱ(PSⅡ). The PSⅡ reaction center uses water as a source of electrons, light energy being used to oxidize water to provide protons and oxygen. How water is oxidized is a difficult problem that has already taken many years of work to understand, however, both the structure of oxygen evolving complex(OEC) and the mechanism of water oxidation still remain to be understood. In this review, we collected the current research results on this area and it will hopefully stimulate further work on the structure of oxygen evolving complex and the mechanism of water oxidation.
