cytochrome b, partial (mitochondrion) [Gerbillus amoenus]

Protein Classification

cytochrome b( domain architecture ID 999999)

cytochrome b is a component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex) that is part of the mitochondrial respiratory chain; contributes to the generation of a proton gradient across the mitochondrial membrane that is then used for ATP synthesis
