The incorporation of DL-[4-2H2,5-13C] ornithine into clavulanic acid and N-acetylglycylclavaminic acid
Abstract
Both the carbon and deuterium label of DL-[4-2H2,5-13C] ornithine were incorporated into the novel β-lactam metabolite N-acetylglycylclavaminic acid, whereas only the carbon label was incorporated into clavulanic acid.
