glutathione s-transferase gsts catalyze the conjugation of the reduced form Glutathione-S-Transferases as Potential Targets for Modulation Nitric Oxide-Mediated Vasodilation Representation of the conjugation reaction

They display the in vivo antioxidant activities by scavenging directly ROS/RNS (OH, O 2 , H 2 O 2 , NO ) and/or by eliminating indirectly ROS/RNS via the enhancement of activities of antioxidant enzymes (SOD, CAT and GPx) (Fig

In its role as an antioxidant, GSH effectively removes free radicals and other reactive oxygen species through the GPx activity [5], which oxidizes GSH to GSSG, and the action of NADPH-dependent glutathione reductase, which generates GSH [3]

Ferritinophagy can also be induced by cystine deprivation that ultimately leads to ferroptosis [134], a mechanism that we have studied extensively in numerous cancer cell types via manipulation of cystine transport mechanisms [135, 136]
