Biol. Evol. 31:1272-1274(2014). CC -!- FUNCTION: Component of the ubiquinol-cytochrome c reductase complex CC (complex III or cytochrome b-c1 complex) that is part of the CC mitochondrial respiratory chain. The b-c1 complex mediates electron CC transfer from ubiquinol to cytochrome c. Contributes to the generation CC of a proton gradient across the mitochondrial membrane that is then CC used for ATP synthesis. {ECO:0000256|ARBA:ARBA00002566}. CC -!- SUBUNIT: The main subunits of complex b-c1 are: cytochrome b, CC cytochrome c1 and the Rieske protein. {ECO:0000256|ARBA:ARBA00011649}. CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane CC {ECO:0000256|ARBA:ARBA00004448}; Multi-pass membrane protein CC {ECO:0000256|ARBA:ARBA00004448}.
