A model for evolution of oxygen evolving reaction center II of higher plant initiating from a chlorophyll--quinone complex is proposed. The reaction center gradually incorporates pheophytin, Fe and Mn to finally achieve oxidation of water to oxygen. The structural and functional pattern during evolution is proposed to descend from higher order of symmetry to lower one.
提出了一个关于高等植物光系统II放氧反应中心从叶绿素-醌复合物开始进化的模型。反应中心逐渐纳入去镁叶绿素、铁和锰,最终实现水氧化成氧气。进化过程中的结构和功能模式被认为是从更高的对称顺序向更低的对称顺序演变。
