Thermodynamic, Kinetic and Mechanistic Aspects of Photosynthetic Water Oxidation [link]Paper  doi  abstract   bibtex   
Water cleavage into dioxygen and four protons requires the cooperation of four redox equivalents of sufficient oxidizing power. In photosynthesis the 1-electron oxidant is generated by electron ejection from the excited singlet state of a special chlorophyll a complex (P680) with pheophytin a (Pheo) as primary acceptor and the indispensible stabilization through Pheo− reoxidation by a specifically bound plastoquinone (QA). The oxidizing equivalents are transferred from P680+ via a tyrosine residue (Yz) into a manganese containing hole storage unit referred to as HSU(Mn). After accumulation of four holes by a sequential univalent storage process (described by S0→S1→S2→S3→S4) oxygen is evolved and HSU(Mn) returns to state S0 (for review see ref. 1,2).
