== Publication Abstract from PubMed ==
beta-Lactams are the most commonly prescribed class of antibiotics and have had an enormous impact on human health. Thus, it is disquieting that an enzyme called New Delhi metallo-beta-lactamase-1 (NDM-1) can confer Enterobacteriaceae with nearly complete resistance to all beta-lactam antibiotics including the carbapenams. We have determined the crystal structure of Klebsiella pneumoniae apo-NDM-1 to 2.1-A resolution. From the structure, we see that NDM-1 has an expansive active site with a unique electrostatic profile, which we propose leads to a broader substrate specificity. In addition, NDM-1 undergoes important conformational changes upon substrate binding. These changes have not been previously observed in metallo-beta-lactamase enzymes and may have a direct influence on substrate recognition and catalysis.
