CC   -!- FUNCTION: Catalyzes the addition of meso-diaminopimelic acid to the
CC       nucleotide precursor UDP-N-acetylmuramoyl-L-alanyl-D-glutamate (UMAG)
CC       in the biosynthesis of bacterial cell-wall peptidoglycan.
CC       {ECO:0000255|HAMAP-Rule:MF_00208}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-D-glutamate + meso-2,6-
CC         diaminopimelate + ATP = UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-gamma-
CC         D-glutamyl-meso-2,6-diaminopimelate + ADP + phosphate + H(+);
CC         Xref=Rhea:RHEA:23676, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:57791, ChEBI:CHEBI:83900,
CC         ChEBI:CHEBI:83905, ChEBI:CHEBI:456216; EC=6.3.2.13;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00208};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00208};
CC   -!- PATHWAY: Cell wall biogenesis; peptidoglycan biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00208}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00208}.
CC   -!- PTM: Carboxylation is probably crucial for Mg(2+) binding and,
CC       consequently, for the gamma-phosphate positioning of ATP.
CC       {ECO:0000255|HAMAP-Rule:MF_00208}.
CC   -!- SIMILARITY: Belongs to the MurCDEF family. MurE subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00208}.
