The 4 substrates of this enzyme are ATP, D-aspartate, [[beta-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-]], and [[Ala)]n]], whereas its 4 products are [[beta-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-6-N-(beta-D-Asp)-L-]], [[Lys-D-Ala-D-Ala)]n]], ADP, and phosphate.
This enzyme belongs to the family of ligases, specifically those forming carbon-nitrogen bonds as acid-D-ammonia (or amine) ligases (amide synthases). The systematic name of this enzyme class is D-aspartate:[beta-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D -Ala-D-Ala)]n ligase (ADP-forming). Other names in common use include Aslfm, UDP-MurNAc-pentapeptide:D-aspartate ligase, and D-aspartic acid-activating enzyme.
