General annotation (Comments)

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 By similarity.
Catalytic activity	ATP + UDP-N-acetylmuramoyl-L-alanyl-D-glutamate + L-lysine = ADP + phosphate + UDP-N-acetylmuramoyl-L-alanyl-D-glutamyl-L-lysine. HAMAP MF_00208
Pathway	Cell wall biogenesis; peptidoglycan biosynthesis. HAMAP MF_00208
Subcellular location	Cytoplasm By similarity.
Post-translational modification	Carbamoylation is probably crucial for Mg2+ binding and, consequently, for the gamma-phosphate positioning of ATP By similarity.
Sequence similarities	Belongs to the murCDEF family. MurE subfamily.
