Abstract

The amino acid sequence of the zinc-requiring beta-lactamase II from Bacillus cereus strain 569 has been determined. It consists of a single polypeptide chain of 227 residues. It is the only example so far fully characterized of a class B beta-lactamase, and is structurally and mechanistically distinct from both the widely distributed class A beta-lactamases (such as the Escherichia coli RTEM enzyme) and from the chromosomally encoded class C enzymes from Gram-negative bacteria.
