Comments

FUNCTION: Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.
CATALYTIC ACTIVITY: QH₂ + 2 ferricytochrome c = Q + 2 ferrocytochrome c + 2 H⁺.
COFACTOR: Binds 1 2Fe-2S cluster per subunit.
SUBUNIT: The main subunits of complex b-c1 are: cytochrome b, cytochrome c1 and the Rieske protein.
SUBCELLULAR LOCATION: Cell membrane; Single-pass membrane protein.
MISCELLANEOUS: The Rieske protein is a high potential 2Fe-2S protein.
SIMILARITY: Contains 1 Rieske domain.
CAUTION: The sequence reported in PubMed:3004982 was thought to originate from R.sphaeroides but was later shown (PubMed:2821272) to be derived from R.capsulatus.
