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:RU004494}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 [Fe(III)cytochrome c](out) + a quinol = 2
CC         [Fe(II)cytochrome c](out) + a quinone + 2 H(+)(out);

CC         ChEBI:CHEBI:29033, ChEBI:CHEBI:29034, ChEBI:CHEBI:132124;
CC         EC=7.1.1.8; Evidence={ECO:0000256|RuleBase:RU004494};
CC   -!- COFACTOR:
CC       Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:49601;
CC         Evidence={ECO:0000256|RuleBase:RU004494};
CC       Note=Binds 1 [2Fe-2S] cluster per subunit.
CC       {ECO:0000256|RuleBase:RU004494};
CC   -!- SUBUNIT: The main subunits of complex b-c1 are: cytochrome b,
CC       cytochrome c1 and the Rieske protein.
CC       {ECO:0000256|RuleBase:RU004497}.
CC   -!- MISCELLANEOUS: The Rieske protein is a high potential 2Fe-2S
CC       protein. {ECO:0000256|RuleBase:RU004494}.
