Enzyme Information

6.3.2.7

UDP-N-acetylmuramoyl-L-alanyl-D-glutamate--L-lysine ligase.

based on mapping to UniProt Q2FZP6

ATP + UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-D-glutamate + L-lysine = ADP + phosphate + UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-gamma-D- glutamyl-L-lysine.

-!- Involved in the synthesis of a cell-wall peptide. -!- This enzyme adds lysine in some Gram-positive organisms; in others and in Gram-negative organisms EC 6.3.2.13 adds 2,6-diaminopimelate instead.
