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 -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413;
CC Evidence={ECO:0000256|PIRSR:PIRSR038885-2};
CC Note=Binds 2 heme groups non-covalently.
CC {ECO:0000256|PIRSR:PIRSR038885-2};
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}.
