Updated on 10-April-2016
FunctionIsopenicillin N synthase (IPNS) is an iron-dependent enzyme which catalyzes the formation of isopenicillin N (IPN) from the tripeptide aminoadipoyl-cysteine-valine (ACV). IPNS participates in the biosynthesis of penicillin and cephalosporin antibiotics. The active site of IPNS contains an Fe atom. The reaction involves the reduction of O2 molecule to H2O[1]. Structural highlightsIPNS active site contains Fe+2 and the substrate ACV. The Fe+2 ion is pentacoordinated to 3 IPNS side chains, one water molecule and the ACV thiolate moiety[2].
