Lineage for d1sqxc2 (1sqx C:2-260)

  1. Root: SCOPe 2.08
  2. 3021034Class f: Membrane and cell surface proteins and peptides [56835] (69 folds)
  3. 3024525Fold 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. 3024526Superfamily 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. 3024532Family 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. 3024543Protein Mitochondrial cytochrome b subunit, N-terminal domain [81641] (3 species)
    also includes extra transmembrane (linker) helix absent in plants and cyanobacteria subunits
  7. 3024565Species Cow (Bos taurus) [TaxId:9913] [81638] (19 PDB entries)
    Uniprot P00157
