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 WebMar 1, 1994 · We show that the rates of synthesis of cyt b6 and suIV are independent of the presence of the other subunits of the complex but that their stabilization in the thylakoid membranes is a concerted process, with a marked dependence of suIV stability on the presence of cyt b6. In contrast, mature cyt f was stable in the absence of either suIV or ...

WebNov 13, 2024 · The cytochrome b 6 f (cytb 6 f ) complex has a central role in oxygenic photosynthesis, linking electron transfer between photosystems I and II and converting solar energy into a transmembrane ... Web2. Reduced ferredoxin, unable to reduce NADP+ returns the electron to PS I via cytochrome b 6, plastoquinone (PQ), cytochrome-f and plastocyanin. 3. The electron transport is called cyclic because the electron emitted from PS I returns back to PS I passing through several intermediate carriers. Hence, the correct answer is 'Cyt.b6'. WebThe cytochrome B6-F complex mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions. This … ironsufex reddit
