Lineage for d1kb9c2 (1kb9 C:1-261)

  1. Root: SCOP 1.65
  2. 340091Class f: Membrane and cell surface proteins and peptides [56835] (36 folds)
  3. 340659Fold f.21: Heme-binding four-helical bundle [81344] (2 superfamilies)
    core: four transmembrane helices, up-and-down bundle, binds one or two heme groups in between the helices
  4. 340660Superfamily 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. 340666Family f.21.1.2: Cytochrome b of cytochrome bc1 complex (Ubiquinol-cytochrome c reductase) [81642] (1 protein)
    a part (domain) of a larger mitochondrial cytochrome b subunit, separate subunit in plants and cyanobacteria
  6. 340667Protein Mitochondrial cytochrome b subunit, N-terminal domain [81641] (3 species)
    also includes extra transmembrane (linker) helix absent in plants and cyanobacteria subunits
  7. 340668Species Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [81640] (4 PDB entries)
  8. 340671Domain d1kb9c2: 1kb9 C:1-261 [77316]
