CC -!- FUNCTION: Component of the ubiquinol-cytochrome c reductase
CC complex (complex III or cytochrome b-c1 complex) that is part of
CC the mitochondrial respiratory chain. The b-c1 complex mediates
CC electron transfer from ubiquinol to cytochrome c. Contributes to
CC the generation of a proton gradient across the mitochondrial
CC membrane that is then used for ATP synthesis.
CC {ECO:0000256|RuleBase:RU362117}.
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413;
CC Evidence={ECO:0000256|RuleBase:RU362117};
CC Note=Binds 2 heme groups non-covalently.
CC {ECO:0000256|RuleBase:RU362117};
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000256|RuleBase:RU362117}.
CC -!- SIMILARITY: Belongs to the cytochrome b family.
CC {ECO:0000256|RuleBase:RU362117}.
