In enzymology, a desacetoxyvindoline 4-hydroxylase (EC 1.14.11.20) is an enzyme that catalyzes the chemical reaction The 3 substrates of this enzyme are desacetoxyvindoline, 2-oxoglutarate, and O2, whereas its 3 products are deacetylvindoline, succinate, and CO2.
This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen.
The systematic name of this enzyme class is desacetoxyvindoline,2-oxoglutarate:oxygen oxidoreductase (4beta-hydroxylating).
Other names in common use include desacetoxyvindoline 4-hydroxylase, desacetyoxyvindoline-17-hydroxylase, D17H, desacetoxyvindoline,2-oxoglutarate:oxygen oxidoreductase, and (4beta-hydroxylating).
This enzyme participates in terpene indole and ipecac alkaloid biosynthesis.
