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.
CC   -!- CATALYTIC ACTIVITY: QH(2) + 2 ferricytochrome c = Q + 2
CC       ferrocytochrome c + 2 H(+).
CC   -!- COFACTOR: Binds 1 2Fe-2S cluster per subunit (By similarity).
CC   -!- SUBUNIT: The main subunits of complex b-c1 are: cytochrome b,
CC       cytochrome c1 and the Rieske protein.
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Single-pass membrane protein
CC       (Potential).
CC   -!- MISCELLANEOUS: The Rieske protein is a high potential 2Fe-2S
CC       protein.
CC   -!- SIMILARITY: Contains 1 Rieske domain.
