CC -!- FUNCTION: Exhibits glutathione-dependent thiol transferase and
CC dehydroascorbate reductase activities. Has S-(phenacyl)glutathione
CC reductase activity. Has also glutathione S-transferase activity.
CC Participates in the biotransformation of inorganic arsenic and
CC reduces monomethylarsonic acid (MMA) and dimethylarsonic acid.
