Crystal structure of the native class C beta-lactamase from Enterobacter cloacae 908R complexed with BRL42715

Overview

BRL 42715, C6-(N1-methyl-1,2,3-triazolylmethylene)penem, is an active-site-directed inactivator of bacterial -lactamases. The crystal structure of Enterobacter cloacae 908R class C -lactamase in complex with BRL 42715, docking, and energy minimization studies explain stereoselectivity of the binding of C6-(heterocyclic methylene)penems against class C -lactamase.

About this Structure

1Y54 is a Single protein structure of sequence from Enterobacter cloacae with FDT as ligand. Active as Beta-lactamase, with EC number 3.5.2.6 Full crystallographic information is available from OCA.
