UQCRQ [ENSP00000367934]
ubiquinol-cytochrome c reductase, complex III subunit VII, 9.5kDa; This is a component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain. This subunit, together with cytochrome b, binds to ubiquinone
CYC1 [ENSP00000317159]
cytochrome c-1; This is the heme-containing component of the cytochrome b-c1 complex, which accepts electrons from Rieske protein and transfers electrons to cytochrome c in the mitochondrial respiratory chain
