WebThe cytochrome b6f complex is an integral membrane protein complex which catalyzes electron transfer from plastoquinol to plastocyanin and pumps protons across the thylakoid membrane. Its turnover rate in chloroplasts can be up to 300 s −1 (reviewed in Hauska et al., 1983; Hope, 1993; Cramer et al., 1994 ). WebThe PSII reaction center absorbs light at 680 nm, whereas the PSI reaction center absorbs light at 700 nm. The PSII and PSI reaction centers are linked by e – carriers: plastoquinone (PQ), which shuttles an e – from PSII to cytochrome b 6 f; and plastocyanin (PC), which shuttles an e – from cytochrome b 6 f to PSI.
In the process of oxidative phosphorylation, a globular cytochrome cc protein is involved in the electron transfer from the membrane-bound complex III to complex IV. Complex III itself is composed of several subunits, one of which is a b-type cytochrome while another one is a c-type cytochrome. See more Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis.
