SCOP 1.71: Domain d1siwc_: 1siw C:

Lineage for d1siwc_ (1siw C:)

1. Root: SCOP 1.71

2. Class f: Membrane and cell surface proteins and peptides [56835] (49 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.21.3: Respiratory nitrate reductase 1 gamma chain [103501] (1 family)
   possible link between the two other superfamilies: this subunit corresponds to the gamma subunit of a functionally related Formate dehydrogenase N complex but is structurally closer to the Fumarate reductase subunit FrdC

5. Family f.21.3.1: Respiratory nitrate reductase 1 gamma chain [103502] (1 protein)

6. Protein Respiratory nitrate reductase 1 gamma chain [103503] (1 species)

7. Species Escherichia coli [TaxId:562] [103504] (2 PDB entries)

8. Domain d1siwc_: 1siw C: [105592]
   Other proteins in same PDB: d1siwa1, d1siwa2, d1siwb_
   complexed with 3ph, f3s, gdp, hem, sf4
