The crystal structure of isopenicillin N synthase with δ-((L)-α-aminoadipoyl)-(L)-cysteinyl-(D)-methionine reveals thioether coordination to iron.
Isopenicillin N synthase (IPNS) catalyses cyclization of δ-(l-α-aminoadipoyl)-l-cysteinyl-d-valine (ACV) to isopenicillin N (IPN), the central step in penicillin biosynthesis. Previous studies have shown that IPNS turns over a wide range of substrate analogues in which the valine residue of its natu...
