Abstract The glutathione transferases (GSTs) are a family of multi-functional proteins which act as enzymes and also as binding proteins in detoxification processes (1-5). GSTs catalyse the nucleophilic attack of the sulfur atom of reduced glutathione by electrophilic groups in a second substrate. Most GSTs are located in the cytosol,

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.

The glutathione transferase kappa family
Drug Metabolism Reviews, 2011Glutathione transferase (GST) kappa, also named mitochondrial GST, is a very ancient protein family with orthologs in bacteria and eukaryotes. Both the structure and the subcellular localization of GSTK1-1, in mitochondria and peroxisomes, make this enzyme distinct from cytosolic GSTs.

Human glutathione S-transferases
International Journal of Biochemistry, 19941. Multiple forms of glutathione S-transferase (GST) isoenzymes present in human tissues are dimers of subunits belonging to three distinct gene families namely alpha, mu and pi. Only the subunits within each class hybridize to give active dimers. 2.

Human Glutathione S-Transferases
Seminars in Liver Disease, 1998Human glutathione S-transferases (GSTs) are a functionally diverse family of soluble enzymes of detoxification that use reduced glutathione (GSH) in conjugation and reduction reactions. Toxic electrophiles, including a variety of carcinogens, are substrates for the GSTs and after conjugation or reduction they are more easily excreted into bile or urine.

Sigma-class glutathione transferases
Drug Metabolism Reviews, 2011Mammalian cytosolic glutathione transferases (GSTs) can be grouped into seven classes. Of these, the sigma class is also widely distributed in nature, with isoforms found in both vertebrates and invertebrates. It contains examples of proteins that have evolved specialized functions, such as the cephalopod lens S-crystallins, the mammalian hematopoietic

The glutathione peroxidase activity of glutathione S-transferases
Biochimica et Biophysica Acta (BBA) - Enzymology, 1980Glutatione transferases (RX:glutathione R-transferases, EC 2.5.1.18) B and AA were purified from rat liver to investigate the mechanism for their apparent GSH peroxidase activity (GSSG formation). Both transferases catalyze an overall reaction in which loss of cumene hydroperoxide is accompanied by a stoichiometric increase in GSSG.

Glutathione Transferases in the Bioactivation of Azathioprine
2014The prodrug azathioprine is primarily used for maintaining remission in inflammatory bowel disease, but approximately 30% of the patients suffer adverse side effects. The prodrug is activated by glutathione conjugation and release of 6-mercaptopurine, a reaction most efficiently catalyzed by glutathione transferase (GST) A2-2.
