In enzymology, a neoxanthin synthase (EC 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.
