Protein Classification

cytochrome b( domain architecture ID 1000033)

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

 2-174 5.57e-85

Cytochrome b (N-terminus)/b6/petB: Cytochrome b is a subunit of cytochrome bc1, an 11-subunit mitochondrial respiratory enzyme. Cytochrome b spans the mitochondrial membrane with 8 transmembrane helices (A-H) in eukaryotes. In plants and cyanobacteria, cytochrome b6 is analogous to eukaryote cytochrome b, containing two chains: helices A-D are encoded by the petB gene and helices E-H are encoded by the petD gene in these organisms. Cytochrome b/b6 contains two bound hemes and two ubiquinol/ubiquinone binding sites. The C-terminal portion of cytochrome b is described in a separate CD.

Cytochrome b/b6 contains two bound hemes and two ubiquinol/ubiquinone binding sites. The C-terminal domain is involved in forming the ubiquinol/ubiquinone binding sites, but not the heme binding sites. The N-terminal portion of cytochrome b, which contains both heme binding sites, is described in a separate CD.
