OX NCBI_TaxID=8469; RN [1] RP SEQUENCE FROM N.A. RX MEDLINE=99297345; PubMed=10368956; RA Kumazawa Y., Nishida M.; RT "Complete mitochondrial DNA sequences of the green turtle and blue- RT tailed mole skink: statistical evidence for archosaurian affinity of RT turtles."; RL Mol. Biol. Evol. 16:784-792(1999). RN [2] RP SEQUENCE FROM N.A. RX MEDLINE=96073446; PubMed=7476123; RA Kumazawa Y., Nishida M.; RT "Variations in mitochondrial tRNA gene organization of reptiles as RT phylogenetic markers."; RL Mol. Biol. Evol. 12:759-772(1995). 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: 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.
