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 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 Web由psii，cytb6f， psi复合体 及一些其它可移动性电子传递 体串联组成。 有二处是逆电势梯度，即p680至 p680*，p700至p700*，这种逆电势 梯度的“上坡”过程由聚光色 素吸收光能后推动，而电子传 递都是顺电势梯度进行的。 水的氧化与psii电子传递相联 系，nadp+的 ...

Webby cytb6f are coupled to the generation of an electrochemical proton gradient across the chloroplast thylakoid membrane, which is harnessed by ATP synthase to form ATP. The mem-brane location and organization of cytb6f complexes is crucial to their function; it is known that the thylakoid membrane in vas- WebJan 1, 2024 · But there is no indication that PSII forms supercomplexes with Cytb 6 f and it also needs to be established to what extend close proximity of PSII and Cytb6f is beneficial for LEF. In conclusion, the novel types of supercomplexes, described in this study, imply further that the non-stacked grana membrane has a higher level of organization than ...
