Prostaglandin E synthase (EC 5.3.99.3, or PGE synthase) is an enzyme involved in eicosanoid and glutathione metabolism, a member of MAPEG family. It generates prostaglandin E (PGE) from prostaglandin H2. ^{[2] [3]}

The synthase generating PGE2 is a membrane-associated protein.

Biosynthesis of eicosanoids.
