Glutathione-Related Enzymes and Proteins: A Review - PMC
Glutathione synthesis occurs only in the cytosol; thus, the mitochondrial pool is supplied by GSH transport and maintained by reducing its oxidized form via the activity of glutathione reductase. Glutathione passes the mitochondrial outer membrane through the mitochondrial porin, a voltage-dependent anion channel (VDAC).
Glutathione - PMC
The committed pathway of glutathione synthesis in plants has been well established for many years (Rennenberg, 1982; Noctor et al., 2002; Mullineaux and Rausch, 2005). The metabolic route is essentially similar to the pathway in most other …
Glutathione synthesis - PubMed
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.
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.
Glutathione: an overview of biosynthesis and modulation
1998年4月24日 · Glutathione (GSH) is a tripeptide of glutamate, cysteine and glycine that contains an unusual γ -peptide bond between glutamate and cysteine (Fig. 1). Such a bond prevents GSH from being hydrolyzed by most peptidases. GSH is less easily oxidized than its precursors, cysteine and γ -glutamylcysteine.
Glutathione: Overview of its protective roles, measurement, and ...
Glutathione synthesis. The sequential ATP dependent formation of amide bonds between cysteine and the γ-carboxyl group of glutamate and then between glycine and cysteine are shown. GSH can be transported out of cells. This mechanism is physiologically important as hepatocytes supply GSH found in the plasma, ...
Glutathione: an overview of biosynthesis and modulation
1998年4月24日 · Glutathione (L-γ-glutamyl-L-cysteinylglycine, GSH) is synthesized from its constituent amino acids by the sequential action of γ-glutamylcysteine synthetase (γ-GCS) and GSH synthetase. The intracellular GSH concentration, typically 1–8 mM, reflects a dynamic balance between the rate of GSH synthesis and the combined rate of GSH consumption ...
Glutathione synthesis - ScienceDirect
2013年5月1日 · Glutathione (GSH) is a tripeptide, γ-L-glutamyl-L-cysteinylglycine, present in all mammalian tissues at 1–10 mM concentrations (highest concentration in liver) as the most abundant non-protein thiol that defends against oxidative stress.

2023年10月26日 · 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.
Glutathione: an overview of biosynthesis and modulation
1998年4月24日 · Glutathione (GSH; gamma-glutamylcysteinylglycine) is ubiquitous in mammalian and other living cells. It has several important functions, including protection against oxidative stress. It is synthesized from its constituent amino acids by the consecutive actions of gamma-glutamylcysteine synthetase and GSH synthetase. gamma-Glutamylcysteine ...
