WebHere we present a 3.6 Å resolution cryo-electron microscopy (cryo-EM) structure of the dimeric cytb 6 f complex from spinach, which reveals the structural basis for operation of … 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, See more • Structure-Function Studies of the Cytochrome b6f Complex - Current research on cytochrome b6f in William Cramer's Lab at … See more
