Fe-S_biosyn

Fe-S_biosyn
PFAM accession number:PF01521
Interpro abstract (IPR000361):

The proteins in this entry are variously annotated as iron-sulphur cluster insertion protein or Fe/S biogenesis protein. They appear to be involved in Fe-S cluster biogenesis. This family includes IscA, HesB, YadR and YfhF-like proteins. The hesB gene is expressed only under nitrogen fixation conditions [ (PUBMED:10217509) ]. IscA, an 11kDa member of the hesB family of proteins, binds iron and [2Fe-2S] clusters, and participates in the biosynthesis of iron-sulphur proteins. IscA is able to bind at least 2 iron ions per dimer [ (PUBMED:15050828) ]. Other members of this family include various hypothetical proteins that also contain the NifU-like domain ( IPR001075 ) suggesting that they too are able to bind iron and are involved in Fe-S cluster biogenesis. The HesB family are found in species as divergent as Homo sapiens (Human) and Haemophilus influenzae suggesting that these proteins are involved in basic cellular functions [ (PUBMED:8875867) ].
