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:

  1. Root: scop
  2. Class: Membrane and cell surface proteins and peptides [56835]
    Does not include proteins in the immune system
  3. 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
  4. 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

  5. Family: Succinate dehydrogenase/Fumarate reductase transmembrane subunits (SdhC/FrdC and SdhD/FrdD) [81373]
    consists of two homologous non-identical subunits that form a heterodimer; may or may not contain heme groups
