Lineage for Family f.21.2.2: Succinate dehydrogenase/Fumarate reductase transmembrane subunits (SdhC/FrdC and SdhD/FrdD)

  1. Root: SCOPe 2.03
  2. 1454900Class f: Membrane and cell surface proteins and peptides [56835] (57 folds)
  3. 1456466Fold 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. 1456537Superfamily f.21.2: Fumarate reductase respiratory complex transmembrane subunits [81343] (2 families) (S)
    two distinct families: in one family the common fold is contained in a single-chain subunit, in the other it is formed by two chains
  5. 1456555Family f.21.2.2: Succinate dehydrogenase/Fumarate reductase transmembrane subunits (SdhC/FrdC and SdhD/FrdD) [81373] (4 proteins)
    consists of two homologous non-identical subunits that form a heterodimer; may or may not contain heme groups
