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|ARBA:ARBA00002444}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a quinol + 2 Fe(III)-[cytochrome c](out) = a quinone + 2
CC Fe(II)-[cytochrome c](out) + 2 H(+)(out); Xref=Rhea:RHEA:11484,
CC Rhea:RHEA-COMP:10350, Rhea:RHEA-COMP:14399, ChEBI:CHEBI:15378,

CC Evidence={ECO:0000256|ARBA:ARBA00029351,
CC ECO:0000256|RuleBase:RU004494};
CC -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
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. {ECO:0000256|ARBA:ARBA00011649,
CC ECO:0000256|RuleBase:RU004497}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|ARBA:ARBA00004162};
CC Single-pass membrane protein {ECO:0000256|ARBA:ARBA00004162}. Membrane
CC {ECO:0000256|ARBA:ARBA00004167}; Single-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004167}.
CC -!- MISCELLANEOUS: The Rieske protein is a high potential 2Fe-2S protein.
CC {ECO:0000256|RuleBase:RU004494}.
CC -!- SIMILARITY: Belongs to the Rieske iron-sulfur protein family.
CC {ECO:0000256|ARBA:ARBA00010651}.
