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