6-α-Methylpenicillin N was synthesised via known routes from 6-aminopenicillanic acid, and tested as a substrate for recombinant DAOCS and DAOC/DACS. Incubation with DAOCS resulted in conversion of 2-oxoglutarate without oxidation of the penicillin substrate ('uncoupled turnover'). Incubation with DAOC/DACS resulted in oxidation to the cephem aldehyde. This is the first example of substrate-induced 'uncoupled turnover', which has been proposed to be an editing mechanism for these enzymes. Elsevier Science Ltd. All rights reserved.

A process is provided which yields derivatives of cephalosporins and penicillins. The process starts with 7-aminodecephalosporanic acid or 6-APA and reacts with a carbonyl containing compound to form a Schiff's base (imino) adduct. This latter compound is
