SCOPe 2.04: Domain d1kf6p_: 1kf6 P:

Lineage for d1kf6p_ (1kf6 P:)

1. Root: SCOPe 2.04

2. Class f: Membrane and cell surface proteins and peptides [56835] (57 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.21.2.2: Succinate dehydrogenase/Fumarate reductase transmembrane subunits (SdhC/FrdC and SdhD/FrdD) [81373] (7 proteins)
   consists of two homologous non-identical subunits that form a heterodimer; may or may not contain heme groups

6. Protein Fumarate reductase subunit FrdD [81372] (2 species)

7. Species Escherichia coli [TaxId:562] [81371] (6 PDB entries)
   is not known to bind heme
