Electrophoretic polymorphism of glutathione peroxidase
Annals of Human Genetics, 1974SUMMARYA method for the detection of glutathione peroxidase after electrophoresis on starch gel has been devised. Blood samples from 780 persons of Caucasian or Negro origin were studied. An electrophoretically fast enzyme, designated as the Thomas variant, was found in 6·4 % of 392 Negro donors and 0·8 % of 388 Caucasian donors.

Oxidation states of glutathione peroxidase
1984Publisher Summary This chapter discusses a method that has been developed for the reproducible isolation of different oxidized forms of glutathione peroxidase, which can be differentiated by their relative stability and by their reactivity with cyanide.

Glutathione peroxidase and oxidative stress
Toxicology Letters, 1995In this study, overexpression of the cDNA for the major cytoplasmic glutathione peroxidase isoenzyme, GSH Peroxidase 1 (GSHPx-1), in human MCF-7 breast cancer cells has been shown to significantly increase the tolerance of these cells to oxidative stress produced by hydrogen peroxide or by the redox cycling of the quinone-containing anticancer agent ...

Glutathione Peroxidase 4 and Ferroptosis
2016Glutathione peroxidase 4 (Gpx4) is one of eight members of the mammalian glutathione peroxidase family of enzymes. Gpx4 is unique due to its capacity to efficiently reduce phospholipid hydroperoxides. Additionally, it has been recognized that Gpx4 governs a novel form of non-apoptotic cell death, named ferroptosis.

Publisher Summary This chapter presents a procedure for the preparation of glutathione peroxidase, which is regarded as a major protective system against endogenously and exogenously induced lipid peroxidation. Two types of methods are used for determining the activity of glutathione peroxidase.

Glutathione peroxidases are considered essential for the prevention of lipid peroxidation in biomembranes (1). Whereas the “classical” tetrameric Glutathione peroxidases (GPX) only reduce hydroperoxy fatty acids previously cleaved from phospholipids by phospholipases, a monomeric variant called phospholipid hydroperoxide glutathione peroxidase (PHGPX ...

Publisher Summary Glutathione peroxidases catalyze the reduction of hydroperoxides (ROOH) by glutathione (GSH). “R” may be an aliphatic or aromatic organic group or, simply, hydrogen. The products are H 2 O, an alcohol (ROH), and glutathione disulfide (GSSG).
