Low concentrations of cystamine and cystine inactivated human placenta glutathione S-transferase (GST-pi) in cytosolic fraction very effectively, as did the purified enzyme, through the thiol/disulfide exchange reaction. Mixed disulfide formation of GST-pi in cytosol was prevented by thioltransferase existing in
