RX MEDLINE=94141932; PubMed=8308901; RA Arnason U., Gullberg A., Johnsson E., Ledje C.; RT "Comparison between the complete mtDNA sequences of the blue and the RT fin whale, two species that can hybridize in nature."; RL J. Mol. Evol. 37:312-322(1993). RN [2] RP SEQUENCE OF 1-125 FROM N.A. RA Lento G.M., Hickson R.E., Chambers G.K., Penny D.; RL Submitted (AUG-1994) 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 -!- CATALYTIC ACTIVITY: QH(2) + 2 FERRICYTOCHROME C = Q + 2 CC FERROCYTOCHROME C. CC -!- COFACTOR: Two heme groups (b562 and b566) which are not covalently CC bound to the protein (By 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.
