Family: Fumarate reductase respiratory complex cytochrome b subunit, FrdC

duplication: consists of two structural repeats; the heme-binding sites are related by pseudo two fold symmetry

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
   uperfamily
5. Family: Fumarate reductase respiratory complex cytochrome b subunit, FrdC [56910]
   duplication: consists of two structural repeats; the heme-binding sites are related by pseudo two fold symmetry

Protein Domains:

1. Fumarate reductase respiratory complex cytochrome b subunit, FrdC [56911]
   1. Wolinella succinogenes [TaxId: 844] [56913] (8)
