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

  1. Root: SCOP 1.73
  2. 744527Class f: Membrane and cell surface proteins and peptides [56835] (50 folds)
  3. 745424Fold 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
