MurD ligase or UDP-N-acetylmuramoyl-L-alanine:D-glutamate ligase catalyzes the conversion of UDP-N-acetylmuramoyl-L-alanine (UMA), D-glutamate and ATP to UDP-N-acetylmuramoyl-L-alanine-D-glutamate and ADP. MurD is one of four Mur ubiquitin ligase enzymes (MurC, MurD, MurE, MurF) which participate in the biosynthesis of peptidoglycans. All four enzymes are topologically similar and contain N-terminal domain which binds the substrate, an ATP-binding central domain and a C-terminal domain which binds the incorporated amino acid.
