ornithine/arginine in the identical regiochemical sense in all of these natural products, and has established the common intermediacy of the monocyclic β-lactam proclavaminicacid (12) as well. In this paper the quite advanced bicyclic intermediate clavaminicacid (14) has been synthesized in doubly 13C-labeled form by preparative incubation of recombinant clavaminate synthase. The intact and equally efficient
