In enzymology a glutamate–cysteine ligase (EC 6.3.2.2) is an enzyme that catalyzes the chemical reactionATP + L-glutamate + L-cysteine ADP + phosphate + gamma-L-glutamyl-L-cysteineThe 3 substrates of this enzyme are ATP L-glutamate and L-cysteine whereas its 3 products are ADP phosphate and gamma-L-glutamyl-L-cysteine.This enzyme belongs to the family of ligases specifically those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases).
