'''RUBRERYTHRIN'''
===RUBRERYTHRIN===




==Overview==
<!--
We have determined the structure of rubrerythrin, a non-haem iron protein from the anaerobic sulphate-reducing bacterium, Desulfovibrio vulgaris (Hildenborough), by X-ray crystallography. The structure reveals a tetramer of two-domain subunits. Each subunit contains a four-helix bundle surrounding a diiron-oxo site and a C-terminal rubredoxin-like FeS4 domain. The diiron-oxo site contains a larger number of carboxylate ligands and a higher degree of solvent exposure than do those in other diiron-oxo proteins. The four-helix bundle of rubrerythrin closely resembles those of the ferritin and bacterioferritin subunits, suggesting a relationship among these proteins-consistent with the recently demonstrated ferroxidase activity of rubrerythrin.
The line below this paragraph, {{ABSTRACT_PUBMED_8646540}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 8646540 is the PubMed ID number.
