Conjugation of reduced glutathione to a wide number ofexogenous and endogenous hydrophobic electrophiles. Catalyzesisomerization reactions that contribute to the biosynthesis ofsteroid hormones. Efficiently catalyze obligatory double-bondisomerizations of delta(5)-androstene-3,17-dione anddelta(5)-pregnene-3,20-dione, precursors to testosterone andprogesterone, respectively.
