WebApr 24, 1998 · GSH is synthesized intracellularly by the consecutive actions of γ -glutamylcysteine (reaction 1) and GSH (reaction 2) synthetases: l -Glu+ l -Cys+ATP⇔ l - γ -Glu− l -Cys+ADP+Pi (1) l - γ -Glu-Cys+Gly+ATP⇔GSH+ADP+Pi (2) Cysteine is usually the limiting substrate in the synthesis of GSH. WebThe biosynthesis of PCs converges with GSH biosynthesis. The enzyme PCS (EC 2.3.2.15) with two substrate binding sites having different affinity for GSH carries out transpeptidation of GSH to form PC molecule (Fig. 4). Fig. 4. Pathway for biosynthesis of phytochelatins (GSH, glutathione; PCS, phytochelatin synthase).
