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 reduces
CC       monomethylarsonic acid (MMA) and dimethylarsonic acid.
CC       {ECO:0000250|UniProtKB:P78417}.
CC   -!- CATALYTIC ACTIVITY:
