Through hydrolysis, the lactamase enzyme breaks the β-lactam ring open, deactivating the molecule's antibacterial properties. Beta-lactamase enzymatic activity can be detected using nitrocefin, a chromogenic cephalosporin substrate which changes color from yellow to red upon beta-lactamase mediated hydrolysis.

Beta-lactamases hydrolyze (and thereby inactivate) the beta-lactam rings of a variety of susceptible penicillins and cephalosporins. To survive the effects of antibiotics, germs are constantly finding new defense strategies, called “resistance mechanisms.” For example, some Enterobacterales can produce enzymes called extended-spectrum beta-lactamases (ESBLs). What is extended spectrum beta-lactamase? Some germs, such as Escherichia coli (E. coli) and Klebsiella, produce an enzyme called extended spectrum beta-lactamase (ESBL). This enzyme makes the germ harder to treat with antibiotics.
