    The metallo-beta-lactamase from Bacteroides fragilis hydrolyzes a wide range of beta-lactam antibiotics, and is not clinically susceptible to any known beta-lactamase inhibitors. B. fragilis is associated with post-surgery hospital infections, and there has been a recent report of plasmid-mediated dissemination of the enzyme. Effective inhibitors are therefore urgently needed. Knowledge of the three-dimensional structure will aid in the drug design effort.
