SCOP 1.75: Domain d2bs2f1: 2bs2 F:1-254

Lineage for d2bs2f1 (2bs2 F:1-254)

1. Root: SCOP 1.75

2. Class f: Membrane and cell surface proteins and peptides [56835] (58 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

5. Family f.21.2.1: Fumarate reductase respiratory complex cytochrome b subunit, FrdC [56910] (1 protein)
   duplication: consists of two structural repeats; the heme-binding sites are related by pseudo two fold symmetry

6. Protein Fumarate reductase respiratory complex cytochrome b subunit, FrdC [56911] (1 species)

7. Species Wolinella succinogenes [TaxId:844] [56913] (5 PDB entries)

8. Domain d2bs2f1: 2bs2 F:1-254 [129041]
