FunctionMURD_ECOLI Cell wall formation. Catalyzes the addition of glutamate to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanine (UMA).[HAMAP-Rule:MF_00639] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedMur ligases play an essential role in the intracellular biosynthesis of bacterial peptidoglycan, the main component of the bacterial cell wall, and represent attractive targets for the design of novel antibacterials. UDP-N-acetylmuramoyl-L-alanine:D-glutamate ligase (MurD) catalyses the addition of D-glutamic acid to the cytoplasmic intermediate UDP-N-acetylmuramoyl-L-alanine (UMA) and is the second in the series of Mur ligases. MurD ligase is highly stereospecific for its substrate, D-glutamic acid (D-Glu). Here, we report the high resolution crystal structures of MurD in complexes with two novel inhibitors designed to mimic the transition state of the reaction, which contain either the D-Glu or the L-Glu moiety. The binding modes of N-sulfonyl-D-Glu and N-sulfonyl-L-Glu derivatives were also characterised kinetically. The results of this study represent an excellent starting point for further development of novel inhibitors of this enzyme.
