CC   -!- FUNCTION: Conjugation of reduced glutathione to a wide number of
CC       exogenous and endogenous hydrophobic electrophiles. Involved in the
CC       formation of glutathione conjugates of both prostaglandin A2 (PGA2) and
CC       prostaglandin J2 (PGJ2). Participates in the formation of novel
CC       hepoxilin regioisomers. {ECO:0000250|UniProtKB:P09488}.
CC   -!- CATALYTIC ACTIVITY:
