additional information
-
the glutathione reductase activity of TGR exhibits hysteretic behavior regulated by the [GSSG]/[GSH] ratio. This behavior is associated with glutathionylation by GSSG and abolished by deglutathionylation. TGR is glutathionylated at two Cys residues: Cys88 and Cys354 after 1 min incubation with 1 mM GSSG and NADPH. Absence of NADPH did not prevent glutathionylation
