M-CSA #16 Beta-lactamase is a key enzyme in antibiotic resistance, catalysing the cleavage of the essential beta-lactam ring structure in penicillin and cephalosporinase type antibiotics. Substrate specificity varies considerably within the beta-lactamases, with some enzymes preferring penicillins and some cephalosporins.
