CC   -!- FUNCTION: Conjugation of reduced glutathione to a wide number of
CC       exogenous and endogenous hydrophobic electrophiles.
CC   -!- FUNCTION: GST isoenzymes appear to play a central role in the parasite
CC       detoxification system. Other functions are also suspected including a
CC       role in increasing the solubility of haematin in the parasite gut.
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:90779; EC=2.5.1.18;
CC   -!- SUBUNIT: Homodimer.
CC   -!- MISCELLANEOUS: There are at least two isoenzymes of GST in S.japonicum.
CC   -!- SIMILARITY: Belongs to the GST superfamily. Mu family. {ECO:0000305}.
