CC -!- FUNCTION: Exhibits glutathione-dependent thiol transferase activity.
CC Has high dehydroascorbate reductase activity and may contribute to the
CC recycling of ascorbic acid. Participates in the biotransformation of
CC inorganic arsenic and reduces monomethylarsonic acid (MMA).
CC {ECO:0000256|RuleBase:RU368071}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 glutathione + H(+) + methylarsonate = glutathione disulfide
CC + H2O + methylarsonous acid; Xref=Rhea:RHEA:15969, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17826, ChEBI:CHEBI:33409,

CC Evidence={ECO:0000256|ARBA:ARBA00001437,
CC ECO:0000256|RuleBase:RU368071};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 glutathione + L-dehydroascorbate = glutathione disulfide +
CC L-ascorbate; Xref=Rhea:RHEA:24424, ChEBI:CHEBI:38290,
CC ChEBI:CHEBI:57925, ChEBI:CHEBI:58297, ChEBI:CHEBI:58539; EC=1.8.5.1;
CC Evidence={ECO:0000256|ARBA:ARBA00000509,
CC ECO:0000256|RuleBase:RU368071};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=glutathione + RX = a halide anion + an S-substituted
CC glutathione + H(+); Xref=Rhea:RHEA:16437, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16042, ChEBI:CHEBI:17792, ChEBI:CHEBI:57925,
