Quinaldate 4 oxidoreductase

In enzymology, a quinaldate 4-oxidoreductase (EC 1.3.99.18) is an enzyme that catalyzes the chemical reaction

The 3 substrates of this enzyme are quinaldate, acceptor, and H₂O, whereas its two products are kynurenate and reduced acceptor.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with other acceptors. The systematic name of this enzyme class is quinoline-2-carboxylate:acceptor 4-oxidoreductase (hydroxylating). This enzyme is also called quinaldic acid 4-oxidoreductase.
