All cyanobacteria, algae, and plants use a similar water-oxidizing catalyst for water
oxidation. This catalyst is housed in Photosystem II, a membrane-protein complex that …

Oxygenic photosynthesis forms the basis of aerobic life on earth by converting light energy
into biologically useful chemical energy and by splitting water to generate molecular oxygen …

Photosystem II (PSII) catalyses the oxidation of water through a four-step cycle of S i states
(i= 0–4) at the Mn4CaO5 cluster,–, during which an extra oxygen (O6) is incorporated at the …

Life on earth is almost entirely solar-powered. We can get some idea of the enormous
quantity of energy received from the sun by noting that during daylight hours, the sun …

Oxygenic photosynthesis, the principal converter of sunlight into chemical energy on earth,
is catalyzed by four multi-subunit membrane-protein complexes: photosystem I (PSI) …

In this review we examine the structure and function of the extrinsic proteins of Photosystem
II. These proteins include PsbO, present in all oxygenic organisms, the PsbP and PsbQ …

In plants and algae, photosystem II uses light energy to oxidize water to oxygen at a
metalloradical site that comprises a tetranuclear manganese cluster and a tyrosyl radical. A …

This paper investigates the mechanism of water splitting in photosystem II (PSII) as
described by chemically sensible models of the oxygen-evolving complex (OEC) in the S0 …

Dioxygen is thermodynamically hot but kinetically cool, which makes it an ideal reagent for
maximizing biological free energy production and for carrying out difficult chemical …
