Beta-lactamase

Beta-lactamase is an enzyme produced by certain bacteria that provides resistance to beta-lactam antibiotics, such as penicillins, cephalosporins, and carbapenems. These antibiotics contain a beta-lactam ring, which is essential for their antibacterial activity. Beta-lactamase catalyzes the hydrolysis of the beta-lactam ring, rendering the antibiotic inactive and allowing bacteria to survive.
