-glutamate-cysteinyl-synthetase or GCL is in part regulated by glutathione feedback inhibition,[26] which can be partially prevented by an excess of glutamic acid that blocks the regulatory site on the enzyme.[25] Thus, if glutathione is exhausted due to OS, exposure to xenobiotics or inflammation, de novo synthesis of glutathione is up-regulated.[26] Inhibition of GS results in the accumulation of -L-glutamyl-L-cysteine that is converted to cysteine and oxoproline by GCT, and then oxoproline is converted to glutamic acid via 5-oxoprolinase reaction by oxoproplinase
