Cytochrome b6-f complex subunit 5
WebThree of the large subunits (cytochrome b6, cytochrome f, and the Rieske ISP) bind redox-active prosthetic groups. In Chlamydomonas five of the subunits (cytochrome b6, subunit IV, cytochrome f, PetG, and PetL) are encoded in the chloroplast, whereas PetM, PetN, and ISP are encoded in the nucleus ( Table 17.1 ).

WebThe Cyt b 6 f complex in cyanobacteria provides the only known pathway for plastoquinol oxidation and appears to be indispensable for both photosynthesis and heterotrophy. This has precluded the propagation of inactivating mutations and … 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 reaction catalyzed … 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 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
WebAs RNAi repression of PetM and PetC was highly efficient in both young and mature leaves, these data indicate a lifetime of the cytochrome b6f complex of at least 1 week. The switch-off of cytochrome b6f complex biogenesis in mature leaves may represent part of the first dedicated step of the leaf senescence program. 展开 WebThe cytochrome b 6 f complex exists as a dimer, with each monomer possessing four small hydrophobic subunits and four large subunits: cytochrome b 6; subunit IV; cytochrome f; iron sulfur protein [ ISP]. Return to Beginning II. Overall Structure and the Electron/Proton Pathways The dimer has 26 transmembrane helices.
WebJul 20, 2024 · Of these 8 subunits, 4 of the largest of the them are considered as a separate subunit of the complex, as defined by Hurt & Hauska. According to Hurt & Hauska, these 4 subunits consist of c-type cytochrome f (PetA), cytochrome b6 (PetB), the ISP (PetC), and subunit IV (PetD, suIV), which is related to the C-terminal half of bc1 cytochrome b.
