Forms part of the pathway for the biosythesis of the β-lactamase inhibitor clavulanate in Streptomyces clavuligerus. It has been proposed  that L-N2-(2-carboxyethyl)arginine is first converted into an acyl-AMP by reaction with ATP and loss of diphosphate, and that the β-lactam ring is then formed by the intramolecular attack of the β-nitrogen on the activated carboxy group.
