3-hydroxy-2-methylquinolin-4-one 2,4-dioxygenase

In enzymology, a 3-hydroxy-2-methylquinolin-4-one 2,4-dioxygenase (EC number|1.13.11.48) is an enzyme that catalyzes the chemical reaction

:3-hydroxy-2-methyl-1H-quinolin-4-one + O₂ $ightleftharpoons$ N-acetylanthranilate + CO

Thus, the two substrates of this enzyme are 3-hydroxy-2-methyl-1H-quinolin-4-one and O₂, whereas its two products are N-acetylanthranilate and CO.

This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O₂ as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O₂. The systematic name of this enzyme class is 3-hydroxy-2-methyl-1H-quinolin-4-one 2,4-dioxygenase (CO-forming). This enzyme is also called (1H)-3-hydroxy-4-oxoquinaldine 2,4-dioxygenase.
