Protein
Isopenicillin N synthase
Gene
pcbC
Organism
Amycolatopsis lactamdurans (Nocardia lactamdurans)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Removes, in the presence of oxygen, 4 hydrogen atoms from delta-L-(alpha-aminoadipyl)-L-cysteinyl-D-valine (ACV) to form the azetidinone and thiazolidine rings of isopenicillin.

Catalytic activityi

N-((5S)-5-amino-5-carboxypentanoyl)-L-cysteinyl-D-valine + O2 = isopenicillin N + 2 H2O.

Cofactori

Iron.
Ascorbate.
