6 beta-Bromopenicillanic acid inactivates beta-lactamase I. 1979

V Knott-Hunziker, and B S Orlek, and P G Sammes, and S G Waley

The inactivation of beta-lactamase I by preparations of 6alpha-bromopenicillanic acid showed unexpected kinetic features that indicated that the active species was the 6beta-epimer. Samples containing 6beta-bromopenicillanic acid have been synthesized and shown to inactivate the enzyme in a rapid stoicheiometric reaction.
