![]() | Class f: Membrane and cell surface proteins and peptides [56835] (36 folds) |
![]() | Fold f.21: Heme-binding four-helical bundle [81344] (2 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] (4 proteins) consists of two homologous non-identical subunits that form a heterodimer; may or may not contain heme groups |
