The interaction of the RTEM beta-lactamase with two derivatives of olivanic acid has been studied. The compound MM22382 (1) behaves simply as a good substrate for the enzyme and is a relatively ineffective inhibitor. In contrast, the sulfate ester MM13902 (2) is a poor substrate and an excellent inhibitor of the enzyme. The inhibition derives from a branching of the normal hydrolytic pathway of the enzyme. At long times, all the catalytic activity of the enzyme returns. Free sulfate ion is not produced during the interaction with the enzyme, which rules out a mechanistic pathway involving beta elimination between C-6 and C-8. The validity of a number of alternative schemes is assessed.
