Free radicals #21:See alt text 🧪
Fig. 2 from Nat Rev Drug Discov 20, 689–709 (2021). Glutathione metabolism and strategies to increase glutathione. Glutathione (GSH) is synthesized through reactions catalysed by glutamate– cysteine ligase (GCL) and GSH synthetase (GS), with GCL as the rate-limiting enzyme and cysteine as the rate-limiting substrate. Both reduced GSH and glutathione disulfide (GSSG) are exported from cells through multidrug resistance protein (MRP), and extracellular GSH is sequentially metabolized by membrane-bound γ-glutamyl transpeptidase (GGT) into cysteinylglycine and γ-glutamyl products, and dipeptidase hydrolyses cysteinylglycine to cysteine and glycine. The amino acids are transported back into cells and participate in GSH synthesis. N-acetylcysteine (NAC) is deacetylated by esterase action into cysteine, while GSH esters (GSH-E) are directly converted by esterase into GSH. γ-Glutamylcysteine (γ-glu-cys) can bypass GCL, the rate-limiting step for GSH synthesis. Electrophiles cause the activation of NRF2, which regulates the transcription of the two subunits of GCL, and also GS. Some transporters have been identified: ASC, sodium- dependent alanine-serine-cysteine transporter; Xc−, system cystine/ glutamate antiporter. Question marks denote the unidentified transporters/ channels for GSH-E, γ-glu-cys and NAC.
