Ecdysone 20-monooxygenase

In enzymology, an ecdysone 20-monooxygenase is an enzyme that catalyzes the chemical reaction


 * ecdysone + AH2 + O2 $$\rightleftharpoons$$ 20-hydroxyecdysone + A + H2O

The 3 substrates of this enzyme are ecdysone, AH2, and O2, whereas its 3 products are 20-hydroxyecdysone, A, and H2O.

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 oxygen incorporated need not be derive from O miscellaneous. The systematic name of this enzyme class is Ecdysone,hydrogen-donor:oxygen oxidoreductase (20-hydroxylating). Other names in common use include alpha-ecdysone C-20 hydroxylase, and ecdysone 20-hydroxylase.
