A set of 49 high-resolution (<or=2.2 A) structures of the TEM, SHV, and CTX-M class A beta-lactamase families was systematically analyzed to investigate the role of conserved water molecules in the stabilization of the Omega-loop. Overall, 13 water molecules were found to be conserved in at least 45 structures, including two water positions which were found to be conserved in all structures. Of the 13 conserved water molecules, 6 are located at the Omega-loop, forming a dense cluster with hydrog ...[more]
