Prostaglandin-A1 Delta-isomerase

In enzymology, a prostaglandin-A1 Delta-isomerase is an enzyme that catalyzes the chemical reaction


 * (13E)-(15S)-15-hydroxy-9-oxoprosta-10,13-dienoate $$\rightleftharpoons$$ (13E)-(15S)-15-hydroxy-9-oxoprosta-11,13-dienoate

Hence, this enzyme has one substrate, (13E)-(15S)-15-hydroxy-9-oxoprosta-10,13-dienoate, and one product, (13E)-(15S)-15-hydroxy-9-oxoprosta-11,13-dienoate.

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.
