RC STRAIN=#97 {ECO:0000313|EMBL:AFU93285.1}; RX PubMed=23071608; DOI=10.1371/journal.pone.0046662; RA Crete-Lafreniere A., Weir L.K., Bernatchez L.; RT "Framing the salmonidae family phylogenetic portrait: a more complete RT picture from increased taxon sampling."; RL PLoS ONE 7:e46662-e46662(2012). CC -!- FUNCTION: Component of the ubiquinol-cytochrome c reductase CC complex (complex III or cytochrome b-c1 complex) that is part of CC the mitochondrial respiratory chain. The b-c1 complex mediates CC electron transfer from ubiquinol to cytochrome c. Contributes to CC the generation of a proton gradient across the mitochondrial CC membrane that is then used for ATP synthesis. CC {ECO:0000256|RuleBase:RU362117}. CC -!- COFACTOR: CC Name=heme; Xref=ChEBI:CHEBI:30413; CC Evidence={ECO:0000256|RuleBase:RU362117}; CC Note=Binds 2 heme groups non-covalently. CC {ECO:0000256|RuleBase:RU362117}; CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane CC {ECO:0000256|RuleBase:RU362117}. CC -!- SIMILARITY: Belongs to the cytochrome b family.
