Protein Domain : Rubrerythrin, diiron-binding domain IPR003251

Type	Domain
Description	Rubrerythrin (Rr) is a fusion protein containing an N-terminal diiron-binding domain and a C-terminal domain homologous to rubredoxin [ ]. This protein has been related to the response to oxidative stress [, , ]. The 3-D structure of Desulphovibrio vulgaris rubrerythrin has been solved [ ]. The structure reveals a tetramer of two-domainsubunits. In each monomer, the N-terminal 146 residues form a four-α-helix bundle containing the diiron-oxo site (centre I), and the C-terminal 45 residues form a rubredoxin-like FeS4 domain. This entry represents the N-terminal diiron-binding domain of Rr, which has a has a ferritin-like fold [ ].
