Glutathione thioether bonds
WebMay 4, 2024 · The resulting products, chiral glutathione adducts, are further converted by GSH-dependent glutathione lyases catalysing thioether cleavage with formation of oxidised glutathione (GSSG) (Gall et al. 2014a; Picart et al. 2015b). The overall result is a reductive cleavage of the β-O-4 aryl ether bond. WebFormation of lanthionine, a dehydroalanine crosslink, is associated with aging of the human lens and cataractogenesis. In this study we investigated whether modification of lens proteins by glutathione could proceed through an alternative pathway: that is, by the formation of a nonreducible thioether bond between protein and glutathione. Direct …
