Communication between the active site and the allosteric site in class A beta-lactamases.

Bacterial production of beta-lactamases, which hydrolyze beta-lactam type antibiotics, is a common antibiotic resistance mechanism. Antibiotic resistance is a high priority intervention area and one strategy to overcome resistance is to administer antibiotics with beta-lactamase inhibitors in the treatment of infectious diseases. Unfortunately, beta-lactamases are evolving at a rapid pace with new inhibitor resistant mutants emerging every day, driving the design and development of novel beta-lactamase inhibitors.
