Function

Function:
Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles. Catalyzes isomerization reactions that contribute to the biosynthesis of steroid hormones. Efficiently catalyze obligatory double-bond isomerizations of delta(5)-androstene-3,17-dione and delta(5)-pregnene-3,20-dione, precursors to testosterone and progesterone, respectively.
Catalytic Activity:
RX + glutathione = HX + R-S-glutathione.
Kinetics:
BIOPHYSICOCHEMICAL PROPERTIES: Kinetic parameters: KM=23 uM for delta(5)-androstene-3,17-dione
