beta-Lactams are the most prescribed antibacterials for the treatment
of bacterial infections. Bacteria have developed mechanisms to resist
the action of beta-lactam drugs, of which the catalytic function of be
ta-lactamase is the most important, These enzymes catalyse hydrolysis
of beta-lactam antibiotics, whereby the drug is destroyed. This review
offers a perspective on the function of these enzymes and their clini
cal implications.
