Metallo-β-lactamases:  Novel Weaponry for Antibiotic Resistance in Bacteria

Abstract excerpt

Metallo-beta-lactamases are broad-spectrum zinc enzymes, able to inactivate most clinically useful beta-lactam antibiotics. Their structural and functional diversity has thus far limited the understanding of their catalytic mechanism, therefore thwarting the rational design of a common inhibitor. On the basis of the recent availability of structures of enzyme-product complexes and novel mechanistic studies, here,...
