OX NCBI_TaxID=245787 {ECO:0000313|EMBL:AAQ90240.1}; RN [1] {ECO:0000313|EMBL:AAQ90240.1} RP NUCLEOTIDE SEQUENCE. RC STRAIN=1561 {ECO:0000313|EMBL:AAQ90240.1}; RA Andrade A.F.B., Bovicino C.R., Briani D.C., Kasahara S.; RT "Karyologic diversification and phylogenetic relationships of the RT genus Thalpomys (Rodentia, Sigmodontinae)."; RL Submitted (MAY-2003) to the EMBL/GenBank/DDBJ databases. 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.
