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 b6/f complex subunit IV; This model describes the subunit IV of the cytochrome b6/f complex. The cyt b6/f complex is central to the functions of the oxygenic phosynthetic electron transport in cyanobacteria and its equivalents in algae and higher plants. Energetically, on the redox scale the cytb6/f complex is placed below the other components - Q(A); Q(B) of the photosystem II in the Z-scheme, along the pathway of the electron transport. The complex is made of the following subunits: cytochrome f; cytochrome b6; Rieske 2Fe-2S; and subunits IV; V; VI; VII. Subunit IV is one of the principal subunits for the binding of the redox prosthetic groups. Each monomer of the complex contains a molecule of chlorophyll a and beta-carotene.

 1-174 3.07e-81

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.

 175-300 1.58e-39

Cytochrome b(C-terminus)/b6/petD: 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 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.

 211-264 3.60e-09

cytochrome b6/f complex subunit IV; This model describes the subunit IV of the cytochrome b6/f complex. The cyt b6/f complex is central to the functions of the oxygenic phosynthetic electron transport in cyanobacteria and its equivalents in algae and higher plants. Energetically, on the redox scale the cytb6/f complex is placed below the other components - Q(A); Q(B) of the photosystem II in the Z-scheme, along the pathway of the electron transport. The complex is made of the following subunits: cytochrome f; cytochrome b6; Rieske 2Fe-2S; and subunits IV; V; VI; VII. Subunit IV is one of the principal subunits for the binding of the redox prosthetic groups. Each monomer of the complex contains a molecule of chlorophyll a and beta-carotene.
