1. Root: SCOPe 2.08

2. Class f: Membrane and cell surface proteins and peptides [56835] (69 folds)

3. Fold 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. Superfamily f.21.2: Fumarate reductase respiratory complex transmembrane subunits [81343] (2 families)
   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
