Function

Function:
Exhibits glutathione-dependent thiol transferase activity. Has high dehydroascorbate reductase activity and may contribute to the recycling of ascorbic acid. Participates in the biotransformation of inorganic arsenic and reduces monomethylarsonic acid (MMA).
Catalytic Activity:
RX + glutathione = HX + R-S-glutathione.
Active Site:
ACT_SITE 32 32 Nucleophile.
