WebApr 11, 2014 · GSH/GSSG ratio should be maintained to optimize the GSH redox system. GCL, the rate-limiting enzyme of GSH synthesis, is composed of a catalytic subunit (GCLC) and a modulating subunit (GCLM). GCLC is the component that performs the amino acid linkage between glutamine and cysteine, whereas GCLM modulates the activity of GCLC … WebGCL from plants was shown to be activated by the formation of an intramolecular disulfide bond under oxidizing conditions [43,44]. Animal GCL activity and GSH synthesis are regulated by a GSH-dependent feedback inhibition, the availability of cysteine, and the amount and ratio of the catalytic and regulatory GCL subunit [37,38,45–48].
