CC -!- FUNCTION: Glutathione S-transferase that catalyzes the nucleophilic
CC attack of the sulfur atom of glutathione on the electrophilic groups of
CC a wide range of exogenous and endogenous compounds. Involved in the
CC formation of glutathione conjugates of both prostaglandin A2 (PGA2) and
CC prostaglandin J2 (PGJ2). It also catalyzes the isomerization of D5-
CC androstene-3,17-dione (AD) into D4-androstene-3,17-dione and may
CC therefore play an important role in hormone biosynthesis. Through its
CC glutathione-dependent peroxidase activity toward the fatty acid
CC hydroperoxide (13S)-hydroperoxy-(9Z,11E)-octadecadienoate/13-HPODE it
CC is also involved in the metabolism of oxidized linoleic acid.
