The enzyme, ecdysone oxidase, which may or may not belong to the family of oxidoreductases, has two substrates including ecdysone and O2.
In enzymology, an ecdysone oxidase (EC ) is an enzyme that catalyzes the chemical reaction This enzyme may or may not belong to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. Thus, the two substrates of this enzyme are ecdysone and O2, whereas its two products are 3-dehydroecdysone and H2O2.
