In enzymology a prostaglandin-A1 Delta-isomerase (EC 5.3.3.9) is an enzyme that catalyzes the chemical reaction(13E)-(15S)-15-hydroxy-9-oxoprosta-1013-dienoate (13E)-(15S)-15-hydroxy-9-oxoprosta-1113-dienoateHence this enzyme has one substrate (13E)-(15S)-15-hydroxy-9-oxoprosta-1013-dienoate (Prostaglandin A1 or PGA1) and one product (13E)-(15S)-15-hydroxy-9-oxoprosta-1113-dienoate (Prostaglandin C1).This enzyme belongs to the family of isomerases specifically those intramolecular oxidoreductases transposing C=C bonds.
