Function

function

Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex) that is part of the mitochondrial respiratory chain. The b-c1 complex mediates electron transfer from ubiquinol to cytochrome c. Contributes to the generation of a proton gradient across the mitochondrial membrane that is then used for ATP synthesis.

Cofactor

Protein has several cofactor binding sites:
heme b (UniProtKB | Rhea| CHEBI:60344 )

Note: Binds 2 heme groups non-covalently.
heme (UniProtKB | Rhea| CHEBI:30413 )

Note: Binds 2 heme groups non-covalently.
