Beta-lactamase

Template:STRUCTURE 3bm6

Beta-lactamase (Blac) are enzymes which make bacteria resistant to β-lactam antibiotics by breaking their β-lactam ring. Blac are classified according to their resistance targets. Class C are cephalosporinases; Class A are broad-spectrum; Class B are metalloenzymes; Class D are cloxacilanases. Carbapenemase (Car) are Blac with wide hydrolytic capacities. Car can hydrolyze penicillins, cephalosporins, monobactams and carbapenems. Extended-spectrum Blac (ESBL) hydrolyze penicillins but not cephalosporins.
