In enzymology, a Prostaglandin-A1 Δ-isomerase (EC 5.3.3.9) is an enzyme that catalyzes the chemical reaction Hence, this enzyme has one substrate, (13E)-(15S)-15-hydroxy-9-oxoprosta-10,13-dienoate (Prostaglandin A1 or PGA1), and one product, (13E)-(15S)-15-hydroxy-9-oxoprosta-11,13-dienoate (Prostaglandin C1).
This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases transposing C=C bonds.
The systematic name of this enzyme class is (13E)-(15S)-15-hydroxy-9-oxoprosta-10,13-dienoate Delta10-Delta11-isomerase.
This enzyme is also called prostaglandin A isomerase.
