Lineage for Protein: Cytochrome b6 subunit of the cytochrome b6f complex

  1. Root: SCOP 1.71
  2. 619386Class f: Membrane and cell surface proteins and peptides [56835] (49 folds)
  3. 620137Fold f.21: Heme-binding four-helical bundle [81344] (3 superfamilies)
    core: four transmembrane helices, up-and-down bundle, binds one or two heme groups in between the helices
  4. 620138Superfamily f.21.1: Transmembrane di-heme cytochromes [81342] (2 families) (S)
    Three of the four heme-ligands are conserved between the two families; both heme groups bind similarly but not identically
  5. 620144Family f.21.1.2: Cytochrome b of cytochrome bc1 complex (Ubiquinol-cytochrome c reductase) [81642] (2 proteins)
    a part (domain) of a larger mitochondrial cytochrome b subunit, separate subunit in plants and cyanobacteria
  6. 620145Protein Cytochrome b6 subunit of the cytochrome b6f complex [103498] (2 species)

Species:

  1. 620146Chlamydomonas reinhardtii [TaxId:3055] [103500] (1 PDB entry)
  2. 620148Mastigocladus laminosus [TaxId:83541] [103499] (1 PDB entry)
