== Function ==

'''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 class A''' (ESBL) hydrolyze penicillins but not cephalosporins.
