Metabolic pathway of arachidonic Acid

We have studied E3, E4, E5, and E6 enzymes

E1 = PGH synthase (Cyclooxygenase); E2 = PGD synthase; E3 = PGE synthase (cPGES, mPGES-1, mPGES-2); E4 = PGH 9,11-endoperoxide reductase (PGFS-1); E5 = PGD 11-ketoreductase (PGFS-1); E6 = PGE 9-ketoreductase (PGFS-2).
