Publication Abstract from PubMed
Isopenicillin N synthase (IPNS) is a non-haem iron oxidase that catalyses the formation of isopenicillin N from the tripeptide delta-(L-alpha-aminoadipoyl)-L-cysteinyl-D-valine. In this report, we describe the crystal structure of the enzyme with a non-natural L,L,L-tripeptide substrate, delta-(L-alpha-aminoadipoyl)-L-cysteinyl-L-3,3,3,3',3',3'-hexafluorovaline . This structure reveals a strong binding interaction of the tripeptide within the active site and a unique conformation for the non-natural L,L,L-diastereomer. Taken together, these findings provide a possible rationale for the previously observed inhibitory effects of L,L,L-tripeptide substrates on IPNS activity.
