This review describes the progress in our understanding of the structure of the Mn complex in Photosystem II over the last two decades. Emphasis is on the research from our laboratory, especially the results from X-ray absorption spectroscopy, low temperature electron paramagnetic resonance and electron spin echo envelope modulation studies. The importance of the interplay between electron paramagnetic resonance studies and X-ray absorption studies, which has led to a description of the oxidation states of manganese as the enzyme cycles through the Kok cycle, is described. Finally, the path, by which our group has utilized these two important methods to arrive at a working structural model for the manganese complex that catalyzes the oxidation of water to dioxygen in higher plants and cyanobacteria, is explained.
本文综述了过去二十年来我们对光合作用系统 II 中锰复合物结构理解的进展。重点介绍了我们实验室的研究工作,特别是 X 射线吸收光谱、低温电子顺磁共振和电子自旋回波调制研究的结果。描述了电子顺磁共振研究和 X 射线吸收研究之间相互作用的重要性,这导致了在 Kok 循环中酶循环过程中锰的氧化态的描述。最后,解释了我们小组如何利用这两种重要方法,提出了一种工作的锰复合物结构模型,该模型催化高等植物和蓝藻中水氧化为氧气。
