Photosynthetic water oxidation: a simplex-scheme of its partial reactions
Photosynthesis of green plants, algae and cyanobacteria is powered by sunlight. It uses water as ultimate donor of electrons for the reduction of CO2 to yield carbohydrates. Photosystem II (PS II), a water^ plastoquinone oxidoreductase, is the key enzyme of oxygenic photosynthesis. It is an integral protein of the thylakoid membrane. PS II is functionally bipartite, its photosynthetic reaction ...
متن کاملThe inorganic biochemistry of photosynthetic water oxidation.
This enzyme, called the photosynthetic water oxidation complex (WOC), liberates protons and electrons needed for energy production and reduction of NADP’ and quinones that are essential for plant growth. The 0, formed in Equation 1 is not essential for plant survival, but is essential for other organisms on Earth, since it is by far the major source of global OL production for the atmosphere. T...
متن کاملExtended protein/water H-bond networks in photosynthetic water oxidation.
Oxidation of water molecules in the photosystem II (PSII) protein complex proceeds at the manganese-calcium complex, which is buried deeply in the lumenal part of PSII. Understanding the PSII function requires knowledge of the intricate coupling between the water-oxidation chemistry and the dynamic proton management by the PSII protein matrix. Here we assess the structural basis for long-distan...
متن کاملPhotosynthetic water oxidation at elevated dioxygen partial pressure monitored by time-resolved X-ray absorption measurements.
The atmospheric dioxygen (O(2)) is produced at a tetramanganese complex bound to the proteins of photosystem II (PSII). To investigate product inhibition at elevated oxygen partial pressure (pO(2) ranging from 0.2 to 16 bar), we monitored specifically the redox reactions of the Mn complex in its catalytic S-state cycle by rapid-scan and time-resolved X-ray absorption near-edge spectroscopy (XAN...
متن کاملFactors influencing hydroxylamine inactivation of photosynthetic water oxidation.
The kinetics of Mn release during NH2OH inactivation of the water oxidizing reaction is largely insensitive to the S-state present during addition of NH2OH. This appears to reflect reduction by NH2OH of higher S-states to a common more reduced state (S0 or S-1) which alone is susceptible to NH2OH inactivation. Sequences of saturating flashes with dark intervals in the range 0.2--5 S-1 effective...
