ID 6.3.2.37 DE UDP-N-acetylmuramoyl-L-alanyl-D-glutamate--D-lysine ligase. AN D-lysine-adding enzyme. AN UDP-MurNAc-L-Ala-D-Glu:D-Lys ligase. CA ATP + D-lysine + UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-D-glutamate = CA ADP + H(+) + N(6)-(UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-gamma-D- CA glutamyl)-D-lysine + phosphate. CC -!- Involved in the synthesis of cell-wall peptidoglycan. CC -!- The D-lysine is attached to the peptide chain at the N(6) position. CC -!- The enzyme from Thermotoga maritima also performs the reaction of CC EC 6.3.2.7. CC -!- Formerly EC 6.3.2.n1. DR Q9WY79, MURE_THEMA ; //
