General description
β-Lactamase produced by bacteria shares sequence homology to penicillin-binding proteins. This enzyme is found in Gram-negative bacteria. β-Lactamases have four molecular classes, named A, B, C, and D. A, C, and D form an acyl-enzyme via active site serine residue. Class B β-lactamases are metalloenzymes, which have a zinc ion at their active site for β-lactam hydrolysis.
