OX NCBI_TaxID=114670; RN [1] RP NUCLEOTIDE SEQUENCE. RA Slowinski J.B., Boundy J., Lawson R.; RT "The phylogenetic relationships of Asian coral snakes (Elapidae: RT Calliophis and Maticora) based on morphological and molecular RT characters."; RL Submitted (DEC-1999) to the EMBL/GenBank/DDBJ databases. 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 two heme groups non-covalently. Heme 1 (or BL or CC b562) is low-potential and absorbs at about 562 nm, and heme 2 (or CC BH or b566) is high-potential and absorbs at about 566 nm (By CC similarity). CC -!- SUBUNIT: The main subunits of complex b-c1 are: cytochrome b, CC cytochrome c1 and the Rieske protein (By similarity). CC -!- SIMILARITY: Belongs to the cytochrome b family.
