Many functions of mitochondrial GSH are significantly different from those of cytosolic GSH. This review considers the peculiarity of functions of mitochondrial GSH and enzymes of its metabolism, especially glutathione peroxidase 4, glutaredoxin 2, and kappa-glutathione transferase.

Biochimica et Biophysica Acta (BBA) - General Subjects, 2013
With increasing evidence that hydroperoxides are not only toxic but rather exert essential physiological functions, also hydroperoxide removing enzymes have to be re-viewed. In mammals, the peroxidases inter alia comprise the 8 glutathione peroxidases (GPx1-GPx8) so far identified.Since GPxs have recently been reviewed under various aspects, we here ...

Annual Review of Pharmacology and Toxicology, 2005
▪ Abstract This review describes the three mammalian glutathione transferase (GST) families, namely cytosolic, mitochondrial, and microsomal GST, the latter now designated MAPEG. Besides detoxifying electrophilic xenobiotics, such as chemical carcinogens, environmental pollutants, and antitumor agents, these transferases inactivate endogenous α,β ...

Glutathione (GSH) is synthesized in the cytoplasm but there is a requirement for glutathione not only in the cytoplasm, but in the other organelles and the extracellular milieu. GSH is also imported into the cytoplasm. The transports of glutathione across these different membranes in different systems have been biochemically demonstrated.

Analytical Biochemistry, 1989
Glutathione monoesters in which the glycine carboxyl group is esterified are effective cellular glutathione delivery agents because they are readily transported into cells and are deesterified intracellularly. In contrast, glutathione itself is not effectively transported into cells. Detailed procedures are given for the preparation of such esters from

Glutathione and glutathione derivatives in immunotherapy
Biological Chemistry, 2016Abstract Reduced glutathione (GSH) is the most prevalent non-protein thiol in animal cells. Its de novo and salvage synthesis serves to maintain a reduced cellular environment, which is important for several cellular functions. Altered intracellular GSH levels are observed in a wide range of pathologies, including several viral ...

Glutathione and glutathione analogues; Therapeutic potentials
Biochimica et Biophysica Acta (BBA) - General Subjects, 2013Glutathione (GSH) and related enzymes are critical to cell protection from toxins, both endogenous and environmental, including a number of anti-cancer cytotoxic agents.Enhancing GSH and associated enzymes represents a longtime and persistent aim in the search for cytoprotective strategies against cancer, neurologic degeneration, pulmonary and ...

Glutathione Peroxidase and Glutathione Reductase Activities toward Glutathione-Derived Antioxidants
Biochemical and Biophysical Research Communications, 1994A new class of glutathione derivatives with antioxidant properties has been prepared by transformation of the NH2 group into a pyrrole ring with various substitutions at the 2 and 5 positions. Due to steric hindrance and/or hydrophobicity of the 2-5-disubstituted pyrrole ring, the reduced glutathione derivatives are poor substrates of the glutathione ...

Glutathione Transferase: New Model for Glutathione Activation
Chemistry – A European Journal, 2008AbstractGlutathione transferases are enzymes of the cellular detoxification system that metabolize a vast spectrum of xenobiotic and endobiotic toxic compounds. They are homodimers or heterodimers and each monomer has an active center composed of a G‐site in which glutathione (GSH) binds and an H‐site for the electrophilic substrate.

[Glutathione and glutathione assays].
Acta medica (Hradec Kralove). Supplementum, 2006Glutathione, the very important intracellular antioxidant, is present in intracelullar environment in milimolar concentrations. Glutathione is a tripeptide molecule, which plays an essential role in the antioxidant system, as well as in maintenance of the intracellular redox state.
