SCOPe 2.06: Domain d2wdql_: 2wdq L:

Lineage for d2wdql_ (2wdq L:)

1. Root: SCOPe 2.06

2. Class f: Membrane and cell surface proteins and peptides [56835] (59 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 Succinate dehydrogenase subunit SdhD [82872] (1 species)
   membrane anchor protein

7. Species Escherichia coli [TaxId:562] [82873] (6 PDB entries)
