Structural Classification of Proteins
Family: Succinate dehydrogenase/Fumarate reductase transmembrane subunits (SdhC/FrdC and SdhD/FrdD)
consists of two homologous non-identical subunits that form a heterodimer; may or may not contain heme groups
Lineage:
Root:
scop
Class:
Membrane and cell surface proteins and peptides
[56835]
Does not include proteins in the immune system
Fold:
Heme-binding four-helical bundle
[81344]
core: four transmembrane helices, up-and-down bundle, binds one or two heme groups in between the helices
Superfamily:
Fumarate reductase respiratory complex transmembrane subunits
[81343]
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
