Lineage for d1kyon3 (1kyo N:1-261)

  1. Root: SCOPe 2.04
  2. 1695624Class f: Membrane and cell surface proteins and peptides [56835] (57 folds)
  3. 1697409Fold 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. 1697410Superfamily 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. 1697416Family f.21.1.2: Cytochrome b of cytochrome bc1 complex (Ubiquinol-cytochrome c reductase) [81642] (3 proteins)
    a part (domain) of a larger mitochondrial cytochrome b subunit, separate subunit in plants and cyanobacteria
  6. 1697427Protein Mitochondrial cytochrome b subunit, N-terminal domain [81641] (3 species)
    also includes extra transmembrane (linker) helix absent in plants and cyanobacteria subunits
  7. Species Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [81640] (5 PDB entries)
  8. 1697434Domain d1kyon3: 1kyo N:1-261 [75907]
