OX NCBI_TaxID=50595 {ECO:0000313|EMBL:QCI61319.1}; RN [1] {ECO:0000313|EMBL:QCI61319.1} RP NUCLEOTIDE SEQUENCE. RA Neves A., Sequeira V., Vieira A.R., Paiva R.B., Paulo O.S., Gordo L.S.; RT "Population structure of the black seabream, Spondyliosoma cantharus, RT throughout the Eastern Atlantic Ocean and Mediterranean Sea."; RL Submitted (JUN-2018) to the EMBL/GenBank/DDBJ databases. 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|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.
