Accumulation of acyl-enzyme intermediates during turnover of penicillins by the class A beta-lactamase of Staphylococcus aureus PC1.

The interaction of dansylpenicillin with the class A Staphylococcus aureus PCI beta-lactamase yielded an accumulating intermediate with fluorescence enhanced beyond that of the substrate. Acid quenching of the reaction mixture yielded a denatured enzyme with 1 molar equivalent of dansyl group covale...
