Antheraxanthin
For this reason, the xanthophyll cycle is sometimes called the violaxanthin cycle. Violaxanthin de-epoxidase is an enzyme that reduces one epoxide group from violaxanthin into a double bond to create antheraxanthin. wikipedia.org

Xanthophyll
In higher plants, there are three carotenoid pigments that are active in the xanthophyll cycle: violaxanthin, antheraxanthin, and zeaxanthin. This conversion of violaxanthin to zeaxanthin is done by the enzyme violaxanthin de-epoxidase (EC 1.23.5.1), while the reverse reaction, i.e. oxidation wikipedia.org

Neoxanthin
It is produced from violaxanthin, but a suspected neoxanthin synthase is still to be confirmed. Two different genes were confirmed to be implied in violaxanthin conversion to neoxanthin in Arabidopsis and tomato. wikipedia.org
