Chains	Enzyme Name	Description	Catalytic Residues
A	beta-lactamase (Class B1) 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.
