ENZYME entry: EC

Accepted Name
(Carboxyethyl)arginine beta-lactam-synthase.
Alternative Name(s)
Beta-lactam synthetase.
Reaction catalysed
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.
