Rubrerythrin (IPR003251)

Short name: Rubrerythrin

Overlapping homologous superfamilies

Domain relationships



Rubrerythrin (Rr), found in anaerobic sulphate-reducing bacteria [PMID: 7830612] and archaea, is a fusion protein containing an N-terminal diiron-binding domain and a C-terminal domain homologous to rubredoxin [PMID: 1657933]. The physiological role of Rr has not been identified.

The 3-D structure of Desulphovibrio vulgaris rubrerythrin has been solved [PMID: 8646540]. The structure reveals a tetramer of two-domain subunits. In each monomer, the N-terminal 146 residues form a four-alpha-helix bundle containing the diiron-oxo site (centre I), and the C-terminal 45 residues form a rubredoxin-like FeS4 domain.
