Photosynthetic water oxidation : the function of two extrinsic

Here, we observed that absence of NDH-1 had little, if any, effect on the functional fractions of PSI under growth conditions, but significantly reduced the functional fractions of PSI when cells of Synechocystis sp. strain PCC 6803 were moved to conditions of multiple stresses.

Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. From:Postharvest Physiology and Biochemistry of Fruits and Vegetables, 2019. Das Photosystem I (PS I) ist ein Proteinkomplex aus mehreren Membranproteinen, der im Zuge der Photosynthese eine Oxidation von Plastocyanin und die Reduktion von Ferredoxin durch absorbierte Photonen katalysiert.

The Gene Ontology (GO) project provides a set of hierarchical controlled vocabulary split into 3 categories:

GO - Biological process i Until now, the functional and structural characterization of monomeric photosystem 1 (PS1) complexes from Thermosynechococcus elongatus has been hampered by the lack of a fully intact PS1 preparation; for this reason, the three-dimensional crystal structure at 2.5 Å resolution was determined with the trimeric PS1 complex [Jordan, P., et al. (2001) Nature 411 (6840), 909−917].

Electron Transfer in Ruthenium-Manganese - CiteSeerX

Abstract. The most important function of photosystem II (PSII) is its action as a water-plastoquinone oxido-reductase. At the expense of light energy, water is split, and oxygen and plastoquinol are formed.

With the availability of genomic information and the structure of photosystem I, one can now probe the functions of photosystem I proteins and cofactors. Photosystem I (PS I) is a chlorophyll (Chl)–protein complex that functions as a light-driven plastocyanin:ferredoxin oxidoreductase. Electron transfer from plastocyanin ( E m ≈ +370 mV) to ferredoxin ( E m ≈ −430 mV) would normally be very endergonic (Δ G ≈ +87 kJ/mol), but is rendered favorable by coupling to absorption of a photon of visible light. 2007-05-01 · Structure, function and regulation of plant photosystem I 1. Introduction. Photosystem I is one of the two membrane-bound photosystems of plants, algae and cyanobacteria that 2. Subunit composition and structure of photosystem I. Fifteen core subunits (PsaA to PsaL, PsaN to PsaP) of PSI are 3.
