Beta-lactamase.
based on mapping to UniProt Q47066
A beta-lactam + H(2)O = a substituted beta-amino acid.
-!- Zinc is only requires in class-B enzymes. -!- A group of enzymes of varying specificity hydrolyzing beta-lactams; some act more rapidly on penicillins, some more rapidly on cephalosporins. -!- Formerly EC 3.5.2.8.
