Beta-lactamase

β-lactamase

Beta-lactamase (β-lactamase) is associated with multiple drug resistance in bacteria. It is able to hydrolyze or degrade the β-lactam ring, which is the core structure and active region of many antibiotic molecules such as penicillin, cephalosporins and kanamycin. Bacteria produce Lactamase in response to beta-lactam antibiotics. Using Lactamase inhibitors inhibits the activity of Lactamase so that it cannot destroy the beta-lactam ring of the antibiotic. Lactamase inhibitors are often used with beta-lactam antibiotics to enhance their effectiveness.
