General annotation (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

QH(2) + 2 ferricytochrome c = Q + 2 ferrocytochrome c + 2 H(+).

Cofactor

Binds 1 2Fe-2S cluster per subunit By similarity.

Subunit structure

The main subunits of complex b-c1 are: cytochrome b, cytochrome c1 and the Rieske protein.

Subcellular location

Cell membrane; Single-pass membrane proteinPotential.

Miscellaneous

The Rieske protein is a high potential 2Fe-2S protein.

Sequence similarities

Contains 1 Rieske domain.
