Gamma-glutamylcysteine synthase (gamma-ECS) (EC 6.3.2.2) catalyses the first step of glutathione (GSH) synthesis, producing gamma-glutamylcysteine (gamma-EC) from L-glutamate and cysteine. In the second step, catalyzed by GSH-S, glycine is added to the C-terminal end of (gamma-EC). GSH is the predominant non-protein thiol in all nearly where it acts as an antioxidant in stress responses and as a mobile pool of reduced sulfur. It is also important in the regulation of plant growth and development. |
