Metallo-beta-lactamase: Structure and Mechanism

Curr Opin Chem Biol. 1999 Oct;3(5):614-22. doi: 10.1016/s1367-5931(99)00017-4.

Abstract

This past year has produced determinations of X-ray crystal structures for three metallo-beta-lactamases and the elucidation of the catalytic mechanisms for a monozinc and a dizinc enzyme. These advances shed light on how such a diverse group of enzymes are evolving to inactivate so efficiently a broad spectrum of beta-lactam antibiotics.
