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).2 glutathione + H(+) + methylarsonate = glutathione disulfide + H2O + methylarsonous acid2 glutathione + L-dehydroascorbate = glutathione disulfide + L-ascorbateglutathione + RX = a halide anion + an S-substituted glutathione + H(+)Belongs to the GST superfamily.
