The cytochrome b6f complex (plastoquinol—plastocyanin reductase; EC 1.10.99.1) is an enzyme found in the thylakoid membrane in chloroplasts of plants, cyanobacteria, and green algae, that catalyzes the transfer of electrons from plastoquinol to plastocyanin. The reaction is analogous to the … See more The cytochrome b6f complex is a dimer, with each monomer composed of eight subunits. These consist of four large subunits: a 32 kDa cytochrome f with a c-type cytochrome, a 25 kDa cytochrome b6 with a low- and … See more The cytochrome b6f complex is responsible for "non-cyclic" (1) and "cyclic" (2) electron transfer between two mobile redox carriers, plastoquinol (QH2) and plastocyanin (Pc): Cytochrome b6f catalyzes the transfer of electrons from … See more In photosynthesis, the cytochrome b6f complex functions to mediate the transfer of electrons and of energy between the two photosynthetic reaction center complexes, Photosystem II and Photosystem I, while transferring protons from the chloroplast … See more • Structure-Function Studies of the Cytochrome b6f Complex - Current research on cytochrome b6f in William Cramer's Lab at Purdue University, USA • UMich Orientation of Proteins in Membranes families/superfamily-3 - Calculated … See more WebThe interaction between plastocyanin and the intact cytochrome bf complex, both from spinach, has been studied by stopped-flow kinetics with mutant plastocyanin to elucidate the site of electron transfer and the …

WebSep 25, 2024 · LEF involves in-series activity of photosystem II (PSII), cytochrome (cyt) b 6 f, and photosystem I (PSI), while CEF involves only PSI and cyt b 6 f. During CEF, electrons released by PSI are reinjected into the photosynthetic electron transport chain at the plastoquinone (PQ) pool or at the stromal side of the cyt b 6 f complex. The fact that … WebThe cytochrome b6f complex (Cyt b6f), which is reduced from the reducing side of PS II by plastoquinone (PQ) and gives up its electrons to plastocyanin, is found between grana … WebThe plastoquinol-cytochrome c 553 /plastocyanin oxidoreductase (Cyt b 6 f complex) catalyzes the rate limiting, quinol-oxidation step in oxygenic photosynthesis. Overall, it transfers electrons between the two photochemical reaction centers (PS II and PS I), is required for cyclic electron flow around PS I, and establishes a transmembrane gradient … signa architect 3.0t 添付文書
