The S2 redox intermediate of the oxygen-evolving complex in photosystem II is present as two spin isomers. The S = 1/2 isomer gives rise to a multiline electron paramagnetic resonance (EPR) signal at g = 2.0, whereas the S = 5/2 isomer exhibits a bro

Water oxidation by photosystem II (PSII) involves the release of O2, electrons, and protons at the oxygen-evolving complex (OEC). These processes are facilitated by a hydrogen-bonded network of amino acid residues and waters surrounding the OEC. It i

The biomimetic oxomanganese complex [MnIII/IV2(μ-O)2(terpy)2(OH2)2](NO3)3 (1; terpy = 2,2′:6′,2″-terpyridine) catalyzes O2 evolution from water when activated by oxidants, such as oxone (2KHSO5·KHSO4·K2SO4). The mechanism of this reaction ha

Photosynthetic water oxidation occurs at the oxygen-evolving complex (OEC) of Photosystem II (PSII). The OEC, which contains a Mn4CaO5inorganic cluster ligated by oxides, waters and amino-acid residues, cycles through five redox intermediates known a

The normal pathway of electron transfer on the electron-acceptor side of photosystem II (PSII) involves electron transfer from quinone A, QA, to quinone B, QB. It is possible to redirect electrons from QA(-) to water-soluble Co(III) complexes, which

The oxygen-evolving complex (OEC) is a Mn4O5Ca cluster embedded in the Photosystem II (PSII) protein complex. As the site of water oxidation, the OEC is connected to the lumen by channels that conduct water, oxygen, and/or protons during the catalyti
