CC   -!- FUNCTION: Component of the ubiquinol-cytochrome c reductase
CC       complex (complex III or cytochrome b-c1 complex), which is a
CC       respiratory chain that generates an electrochemical potential
CC       coupled to ATP synthesis. {ECO:0000256|RuleBase:RU003385}.
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413;
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.
CC       {ECO:0000256|RuleBase:RU003385}.
CC   -!- SIMILARITY: Belongs to the cytochrome b family.
CC       {ECO:0000256|RuleBase:RU003385}.
