Glutathione S-transferase omega-1 (GSTO1 aka monomethylarsonic acid reductase, MMA(V) reductase) is a bifunctional enzyme that has glutathione S-transferase activity and also takes part in the biotransformation of inorganic arsenic. It mediates the reduction of methylarsonate to methylarsonite (Zakharyan et al. 2001).
