In molecular biology the iron-sulfur cluster biosynthesis protein family of includes proteins involved in biogenesis of Fe-S clusters (iron-sulfur cluster insertion protein Fe/S biogenesis protein). This family includes IscA HesB YadR and YfhF-like proteins. The hesB gene is expressed only under nitrogen fixation conditions. IscA an 11 kDa member of the hesB family of proteins binds iron and [2Fe-2S] clusters and participates in the biosynthesis of iron-sulfur proteins.
