GLUTATHIONE SYNTHESIS - PMC
GSH is also a key determinant of redox signaling, vital in detoxification of xenobiotics, modulates cell proliferation, apoptosis, immune function, and fibrogenesis. This review is focused on factors that determine GSH synthesis and pathologies where dysregulation in GSH synthesis may play an important role with emphasis on the liver.
Glutathione synthesis - PubMed
Biosynthesis of GSH occurs in the cytosol in a tightly regulated manner. Key determinants of GSH synthesis are the availability of the sulfur amino acid precursor, cysteine, and the activity of the rate-limiting enzyme, glutamate cysteine ligase (GCL), which is composed of a catalytic (GCLC) and a modifier (GCLM) subunit.
Three-pathway combination for glutathione biosynthesis in
2015年9月16日 · Glutathione (GSH), a pivotal non-protein thiol, can be biosynthesized through three pathways in different organisms: (1) two consecutive enzymatic reactions catalyzed by γ-glutamylcysteine synthetase (Gsh1 or GshA) and glutathione synthetase (Gsh2 or GshB); (2) a bifunctional γ-glutamylcysteine synthetase/glutathione synthetase (GshF); (3) an al...

Glutathione Metabolism and Its Implications for Health
2004年3月1日 · Glutathione (γ-glutamyl-cysteinyl-glycine; GSH) is the most abundant low-molecular-weight thiol, and GSH/glutathione disulfide is the major redox couple in animal cells. The synthesis of GSH from glutamate, cysteine, and glycine is catalyzed sequentially by two cytosolic enzymes, γ-glutamylcysteine synthetase and GSH synthetase.
An Update on Glutathione's Biosynthesis, Metabolism, Functions, …
This review presents a current concept of the synthesis and metabolism of GSH; its main functions in a living organism, and as a precursor and cofactor; data on the use of GSH for medicinal purposes in the prevention and treatment of some diseases, as well as a nutritional strategy to maintain a normal pool of GSH in the body.

2011年12月17日 · GSH is synthesized by the consecutive reactions of the two ATP-consuming enzymes glutamate cysteine ligase (GCL; γ-glutamylcysteine synthetase) and GSH synthetase. GCL generates the dipeptide γGluCys from glutamate and cysteine. GSH synthetase catalyzes the reaction of this dipeptide with glycine to GSH (Fig. 36.1).
