(Carboxyethyl)arginine beta-lactam-synthase.
based on mapping to UniProt P0DJQ7
ATP + L-N(2)-(2-carboxyethyl)arginine = AMP + diphosphate + deoxyamidinoproclavaminate.
-!- Forms part of the pathway for the biosythesis of the beta-lactamase inhibitor clavulanate in Streptomyces clavuligerus. -!- It has been proposed that L-N(2)-(2-carboxyethyl)arginine is first converted into an acyl-AMP by reaction with ATP and loss of diphosphate, and that the beta-lactam ring is then formed by the intramolecular attack of the beta-nitrogen on the activated carboxy group.
