Accepted name: UDP-N-acetylmuramoyl-L-alanyl-D-glutamate—D-lysine ligase
Reaction: ATP + UDP-N-acetyl-α-D-muramoyl-L-alanyl-D-glutamate + D-lysine = ADP + phosphate + UDP-N-acetyl-α-D-muramoyl-L-alanyl-γ-D-glutamyl-Nε-D-lysine
Glossary: muramic acid = 2-amino-3-O-[(R)-1-carboxyethyl]-2-deoxy-D-glucose
Other name(s): UDP-MurNAc-L-Ala-D-Glu:D-Lys ligase; D-lysine-adding enzyme
Systematic name: UDP-N-acetyl-α-D-muramoyl-L-alanyl-D-glutamate:D-lysine γ-ligase (ADP-forming)
Comments: Involved in the synthesis of cell-wall peptidoglycan. The D-lysine is attached to the peptide chain at the N6 position. The enzyme from Thermotoga maritima also performs the reaction of EC, UDP-N-acetylmuramoyl-L-alanyl-D-glutamate—L-lysine ligase.
