XAS of Mn in the Photosynthetic Oxygen, Evolving Complex
Nearly all of the dioxygen which animals and aerobic bacteria use during respiration originates from the photosynthetic oxygen evolving complex (OEC) which is found in the chloroplast thylakoid membranes of higher plants and algae. Four specifically bound Mn are required for OEC activity [l]. These manganese do not exhibit the six line epr spectrum which is characteristic of Mn(IIj in solution,...
متن کاملMetallo-radical hypothesis for photoassembly of (Mn)4-cluster of photosynthetic oxygen evolving complex.
A new hypothetical mechanism is proposed for photoassembly of the (Mn)4-cluster of the photosynthetic oxygen evolving complex (OEC). In this process, a neutral radical of Y(Z) tyrosine plays a role in oxidizing Mn2+ associated with an apo-OEC, and also in abstracting a proton from a water molecule bound to the Mn2+ ion, together with D1-His190. This is in a similar fashion to the metallo-radica...
متن کاملG009 Characterization of the Mn Sites in Manganese Redox Proteins: Mn Catalase and the Photosynthetic Oxygen Evolving
Manganese redox enzymes play crucial roles in a variety of biological systems. These include the photosynthetic oxidation of water m dioxygen, the disproport ionat ion of hydrogen peroxide, the disproport ionat ion of superoxide, and ribonucleotide reduction. The Mn sites in two of these systems, the photosynthetic oxygen evolving complex (OEC) and the Mn catalase from L. planrarum have been ch...
متن کاملArchitecture of the photosynthetic oxygen-evolving center.
Photosynthesis uses light energy to drive the oxidation of water at an oxygen-evolving catalytic site within photosystem II (PSII). We report the structure of PSII of the cyanobacterium Thermosynechococcus elongatus at 3.5 angstrom resolution. We have assigned most of the amino acid residues of this 650-kilodalton dimeric multisubunit complex and refined the structure to reveal its molecular ar...
متن کاملA synthetic model of the Mn₃Ca subsite of the oxygen-evolving complex in photosystem II.
Within photosynthetic organisms, the oxygen-evolving complex (OEC) of photosystem II generates dioxygen from water using a catalytic Mn(4)CaO(n) cluster (n varies with the mechanism and nature of the intermediate). We report here the rational synthesis of a [Mn(3)CaO(4)](6+) cubane that structurally models the trimanganese-calcium-cubane subsite of the OEC. Structural and electrochemical compar...
