δ-(L-α-Amino<1,1,6-¹⁷O/¹⁸O>-adipyl)-L-cystinyl-D-valine was converted into isopenicillin N in cell-free extracts of Cephalosporium acremonium with no loss of ¹⁷O/¹⁸O label as shown by 17O NMR spectroscopy and mass spectrometry.Incubation of unlabelled tripeptide in a cell-free system containing ¹⁷O/¹⁸O enriched water produced isopenicillin N with no incorporation of ¹⁷O/¹⁸O.
