Zool. Syst. Evol. Res. 0:0-0(2016). CC -!- FUNCTION: Component of the ubiquinol-cytochrome c reductase complex CC (complex III or cytochrome b-c1 complex) that is part of the CC mitochondrial respiratory chain. The b-c1 complex mediates electron CC transfer from ubiquinol to cytochrome c. Contributes to the generation CC of a proton gradient across the mitochondrial membrane that is then CC used for ATP synthesis. {ECO:0000256|ARBA:ARBA00002566, CC ECO:0000256|RuleBase:RU362117}. CC -!- COFACTOR: CC Name=heme b; Xref=ChEBI:CHEBI:60344; CC Evidence={ECO:0000256|RuleBase:RU362117}; CC Note=Binds 2 heme groups non-covalently. CC {ECO:0000256|RuleBase:RU362117}; CC -!- SUBUNIT: The cytochrome bc1 complex contains 11 subunits: 3 respiratory CC subunits (MT-CYB, CYC1 and UQCRFS1), 2 core proteins (UQCRC1 and CC UQCRC2) and 6 low-molecular weight proteins (UQCRH/QCR6, UQCRB/QCR7, CC UQCRQ/QCR8, UQCR10/QCR9, UQCR11/QCR10 and a cleavage product of CC UQCRFS1). This cytochrome bc1 complex then forms a dimer. CC {ECO:0000256|ARBA:ARBA00011088}. CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Mitochondrion CC inner membrane {ECO:0000256|ARBA:ARBA00004448}; Multi-pass membrane CC protein {ECO:0000256|ARBA:ARBA00004448}. CC -!- SIMILARITY: Belongs to the cytochrome b family.
