Function
function
Catalyzes the addition of meso-diaminopimelic acid to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanyl-D-glutamate (UMAG) in the biosynthesis of bacterial cell-wall peptidoglycan.
Catalytic activity
- ATP + meso-2,6-diaminoheptanedioate + UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-D-glutamate = ADP + H+ + phosphate + UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-gamma-D-glutamyl-meso-2,6-diaminoheptanedioate
Cofactor
Pathway
Cell wall biogenesis; peptidoglycan biosynthesis.
