mechanism, active site residues are Glu144, Asn146, Lys305, and Lys364, interaction of these residues with the ligands is essential for enzyme activity, especially Glu144 seems to be very important for stabilization of the reaction intermediate, but the active site residues are not essential for the overall enzyme structure |

| 6.3.2.3 | ATP + gamma-L-glutamyl-L-cysteine + glycine = ADP + phosphate + glutathione |
the catalytic mechanism is proposed to proceed via phosphorylation of the dipeptide substrate to yield an acyl phosphate intermediate. This intermediate is subsequently attacked by glycine, followed by loss of inorganic phosphate, leading to glutathione formation |

| 6.3.2.3 | ATP + gamma-L-glutamyl-L-cysteine + glycine = ADP + phosphate + glutathione |
the reaction process involves the formation of an acyl phosphate on the cysteinyl moiety in L-gamma-glutamyl-L-cysteine, followed by the attack of the glycine and formation of an enzyme-product complex, which finally dissociates with the release of GSH, ADP and phosphate |
