Lineage for d1q90b_ (1q90 B:)

  1. Root: SCOP 1.67
  2. 425432Class f: Membrane and cell surface proteins and peptides [56835] (42 folds)
  3. 426093Fold 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. 426094Superfamily 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
