IUBMB Enzyme Nomenclature


Accepted name: prostaglandin-D synthase

Reaction: (5Z,13E,15S)-9α,11α-epidioxy-15-hydroxyprosta-5,13-dienoate = (5Z,13E,15S)-9α,15-dihydroxy-11-oxoprosta-5,13-dienoate

Other name(s): prostaglandin-H2 Δ-isomerase; prostaglandin-R-prostaglandin D isomerase; PGH-PGD isomerase; prostaglandin endoperoxide Δ-isomerase; prostaglandin D synthetase; (5Z,13E)-(15S)-9a,11a-epidioxy-15-hydroxyprosta-5,13-dienoate D-isomerase

Systematic name: (5Z,13E,15S)-9α,11α-epidioxy-15-hydroxyprosta-5,13-dienoate Δ-isomerase

Comments: Brings about the opening of the epidioxy bridge. Some enzymes require glutathione.
