Lineage for d1qcrc3 (1qcr C:2-260)

  1. Root: SCOPe 2.05
  2. 1955192Class f: Membrane and cell surface proteins and peptides [56835] (57 folds)
  3. 1957178Fold 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. 1957179Superfamily 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. 1957185Family 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. 1957196Protein Mitochondrial cytochrome b subunit, N-terminal domain [81641] (3 species)
    also includes extra transmembrane (linker) helix absent in plants and cyanobacteria subunits
  7. 1957218Species Cow (Bos taurus) [TaxId:9913] [81638] (17 PDB entries)
    Uniprot P00157
  8. 1957239Domain d1qcrc3: 1qcr C:2-260 [75932]
