Involved with EC 126.96.36.199 (D-alanine—D-alanine ligase), EC 188.8.131.52 (UDP-N-acetylmuramoyl-L-alanyl-D-glutamate—L-lysine ligase) or EC 184.108.40.206 (UDP-N-acetylmuramoylalanyl-D-glutamate—2,6-diaminopimelate ligase), EC 220.127.116.11 (UDP-N-acetylmuramate—L-alanine ligase) and EC 18.104.22.168 (UDP-N-acetylmuramoylalanine—D-glutamate ligase) in the synthesis of a cell-wall peptide. This enzyme also catalyses the reaction when the C-terminal residue of the tripeptide is meso-2,4-diaminoheptanedioate (acylated at its L-centre), linking the D-Ala—D-Ala to the carboxy group of the L-centre. This activity was previously attributed to EC 22.214.171.124, which has since been deleted.
