Biogeogr. 41:2162-2172(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 cytochrome bc1 complex contains 3 respiratory subunits CC (MT-CYB, CYC1 and UQCRFS1), 2 core proteins (UQCRC1 and UQCRC2) and CC probably 6 low-molecular weight proteins. CC {ECO:0000256|ARBA:ARBA00011660}. CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane CC {ECO:0000256|ARBA:ARBA00004448}; Multi-pass membrane protein CC {ECO:0000256|ARBA:ARBA00004448}.
