WebMar 6, 2024 · The complex contains 11 subunits, a 2-iron ferredoxin, cytochromes b and c1 and belongs to the family of oxidoreductase enzymes. It accepts electrons from coenzyme Q in electron transport and passes them off to cytochrome c. In this cycle, known as the Q cycle, electrons arrive from CoQ in pairs, but get passed to cytochrome c individually. WebMany respiratory cytochromes contain two molecules of b-type heme in their transmembrane domains.A long-standing goal in cytochrome design is therefore the creation of a minimal protein architecture that can house two b-type hemes at an appropriate distance and orientation for electron transport within, and across, a cellular lipid …
