Synonyms
complex III, cytochrome bc(1) complex, cytochrome bc1 complex, ubiquinol-cytochrome c oxidoreductase complex, ubiquinol-cytochrome-c reductase complex, CoQH2-cytochrome c reductase complex, coenzyme Q-cytochrome c oxidoreductase complex, coenzyme Q-cytochrome c reductase complex, electron transport complex III

Definition
A protein complex that transfers electrons from ubiquinol to cytochrome c and translocates two protons across a membrane. The complex contains a core structure of three catalytic subunits: cytochrome b, the Rieske iron sulfur protein (ISP), and cytochrome c1, which are arranged in an integral membrane-bound dimeric complex; additional subunits are present, and vary among different species.
