UDP -N- acetylmuramoyl- L -alanine: D -glutamate (MurD) ligase catalyses, the addition of d -glutamate to the nucleotide precursor UDP -N-, acetylmuramoyl- L -alanine (UMA). The crystal structures of three, complexes of Escherichia coli MurD with a variety of substrates and, products have been determined to high resolution. These include (1) the, quaternary complex of MurD, the substrate UMA, the product ADP, and Mg2+, (2) the quaternary complex of MurD, the substrate UMA, the product ADP, and Mn2+, and (3) the binary complex of MurD with the product UDP - N-, acetylmuramoyl- L -alanine- D -glutamate (UMAG). The reaction mechanism, supported by these structures proceeds by the phosphorylation of the, C-terminal carboxylate group of UMA by the gamma-phosphate group of ATP to, form an acyl-phosphate intermediate, followed by the nucleophilic attack, by the amino group of D-glutamate to produce UMAG. A key feature in the, reaction intermediate is the presence of two magnesium ions bridging, negatively charged groups.
