OX NCBI_TaxID=9958; RN [1] RP NUCLEOTIDE SEQUENCE [GENOMIC DNA]. RX MEDLINE=21313697; PubMed=11420362; RA Matthee C.A., Davis S.K.; RT "Molecular insights into the evolution of the family Bovidae: a RT nuclear DNA perspective."; RL Mol. Biol. Evol. 18:1220-1230(2001). CC -!- FUNCTION: Component of the ubiquinol-cytochrome c reductase CC complex (complex III or cytochrome b-c1 complex), which is a CC respiratory chain that generates an electrochemical potential CC coupled to ATP synthesis (By similarity). CC -!- COFACTOR: Binds 2 heme groups noncovalently (By similarity). CC -!- SUBUNIT: The main subunits of complex b-c1 are: cytochrome b, CC cytochrome c1 and the Rieske protein (By similarity). CC -!- MISCELLANEOUS: Heme 1 (or BL or b562) is low-potential and absorbs CC at about 562 nm, and heme 2 (or BH or b566) is high-potential and CC absorbs at about 566 nm (By similarity). CC -!- SIMILARITY: Belongs to the cytochrome b family.
