Stereospecificity of carbon–sulphur bond formation in penicillin biosynthesis

Abstract
The conversion of the tripeptide (L-α-amino-δ-adipoyl)-L-cysteinyl-D-valine (α-amino-δ-adipoyl = 5-amino-5-carboxypentanoyl) into isopenicillin N by the enzyme isopenicillin N synthetase has been shown to proceed with complete retention of stereochemistry; a similar result was observed during penicillin formation with isoleucinyl and allo-isoleucinyl tripeptides.
