Prostaglandin G/H synthase 2 (PTGS2) exhibits a dual catalytic activity, a cyclooxygenase and a peroxidase. The peroxidase function converts prostaglandin G2 (PGG2) to prostaglandin H2 (PGH2) via a two-electron reduction (Hamberg et al. 1973, Hla & Neilson 1992, Swinney et al. 1997, Barnett et al. 1994).
