b-lactam antibiotics are useful and frequently prescribed antibiotics that share a common structure and mehanism of action-inhibition of the bacterial peptidoglycan cell wall. Important classes of penicilins include penicilin G and V, which are highly active against susceptible gram-positive cocci; ...

Metallo-β-lactamases (mβls) cause bacterial resistance toward a broad spectrum of β-lactam antibiotics by catalyzing the hydrolytic cleavage of the four-membered β-lactam ring, thus inactivating the drug. Minutiae of the mechanism of these enzymes are still not well understood, and reports abo...
