CC -!- FUNCTION: Component of the ubiquinol-cytochrome c reductase complex
CC (complex III or cytochrome b-c1 complex), which is a respiratory chain
CC that generates an electrochemical potential coupled to ATP synthesis.
CC {ECO:0000256|RuleBase:RU003385}.
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000256|RuleBase:RU003385};
CC Note=Binds 2 heme groups non-covalently.
CC {ECO:0000256|RuleBase:RU003385};
CC -!- SUBUNIT: The main subunits of complex b-c1 are: cytochrome b,
CC cytochrome c1 and the Rieske protein. {ECO:0000256|ARBA:ARBA00011649,
CC ECO:0000256|RuleBase:RU003385}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi-
CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the cytochrome b family.
CC {ECO:0000256|RuleBase:RU003385}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:GAN54664.1}.
