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.
