Systematic name:
UDP-N-acetyl-α-D-muramoyl-L-alanyl-D-glutamate:meso-2,6-diaminoheptanedioate γ-ligase (ADP-forming)



Involved in the synthesis of a cell-wall peptide. This enzyme adds diaminopimelate in Gram-negative organisms and in some Gram-positive organisms; in others EC (UDP-N-acetylmuramoyl-L-alanyl-D-glutamate—L-lysine ligase) adds lysine instead. It is the amino group of the L-centre of the diaminopimelate that is acylated.
