Class f: Membrane and cell surface proteins and peptides [56835] (69 folds) |
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 |
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 |
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 |
Protein Fumarate reductase subunit FrdD [81372] (2 species) |
Species Escherichia coli [TaxId:562] [81371] (6 PDB entries) is not known to bind heme |
