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, 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 See more WebCytochrome B6-F complex Fe-S subunit.

WebApr 11, 2024 · The thylakoid membrane is covered with cyt B6F. Two H+ are released into the lumen, and two electrons are transferred to Cyt B6f once PQH2 reaches there. Cytochrome b6f → Phycocyanin: The next protein receives the electrons, which are now transmitted once again one at a time. The potential of cytot b6f is greater than that of … WebThis study provides evidence for enhanced electron flow from the stromal compartment of the photosynthetic membranes to P700+ via the cytochrome b6/f complex (Cyt b6/f) in leaves of Cucumis sativus L. submitted to chilling-induced photoinhibition.
