In enzymology a glutamate-putrescine ligase (EC 6.3.1.11) is an enzyme that catalyzes the chemical reactionATP + L-glutamate + putrescine ADP + phosphate + gamma-L-glutamylputrescineThe 3 substrates of this enzyme are ATP L-glutamate and putrescine whereas its 3 products are ADP phosphate and gamma-L-glutamylputrescine.This enzyme belongs to the family of ligases specifically those forming carbon-nitrogen bonds as acid-D-ammonia (or amine) ligases (amide synthases).
