Isopenicillin N synthase (IPNS) is a non-haem iron oxidase that catalyses the formation of bicyclic isopenicillin N from delta-(L-alpha-aminoadipoyl)-L-cysteinyl-D-valine (ACV). In this study we report a novel activity for the iron of the IPNS active site, which behaves as a Lewis acid to catalyse the elimination of HF from the fluorinated substrate analogue, delta-(L-alpha-aminoadipoyl)-L-cysteinyl-D-beta-fluorovaline (ACbetaFV) ...
