In enzymology, a neoxanthin synthase (EC 5.3.99.9) is an enzyme that catalyzes the chemical reaction:
- violaxanthin neoxanthin
Hence, this enzyme has one substrate, violaxanthin, and one product, neoxanthin.
This enzyme belongs to the family of isomerases, specifically a class of other intramolecular oxidoreductases. The systematic name of this enzyme class is violaxanthin---neoxanthin isomerase (epoxide-opening). This enzyme is also called NSY. This enzyme participates in carotenoid biosynthesis - general.
