DE Cytochrome b (Ubiquinol-cytochrome-c reductase complex cytochrome b DE subunit) (Cytochrome b-c1 complex subunit 3) (Complex III subunit 3) DE (Complex III subunit III). GN Name=MT-CYB; Synonyms=COB, CYTB, MTCYB; OS Oryx gazella (Gemsbok). OG Mitochondrion. OC Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; OC Mammalia; Eutheria; Laurasiatheria; Cetartiodactyla; Ruminantia; OC Pecora; Bovidae; Hippotraginae; Oryx. 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 non-covalently (By similarity). CC -!- SUBUNIT: The bc1 complex contains 11 subunits: 3 respiratory CC subunits (cytochrome b, cytochrome c1 and Rieske/UQCRFS1), 2 core CC proteins (UQCRC1/QCR1 and UQCRC2/QCR2) and 6 low-molecular weight CC proteins (UQCRH/QCR6, UQCRB/QCR7, UQCRQ/QCR8, UQCR10/QCR9, CC UQCR11/QCR10 and a cleavage product of Rieske/UQCRFS1) (By CC similarity). CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass CC membrane 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.
