3-hydroxy-4-oxoquinoline 2,4-dioxygenase

In enzymology, a 3-hydroxy-4-oxoquinoline 2,4-dioxygenase (EC number|1.13.11.47) is an enzyme that catalyzes the chemical reaction

:3-hydroxy-1H-quinolin-4-one + O₂ $ightleftharpoons$ N-formylanthranilate + CO

Thus, the two substrates of this enzyme are 3-hydroxy-1H-quinolin-4-one and O₂, whereas its two products are N-formylanthranilate 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-1H-quinolin-4-one 2,4-dioxygenase (CO-forming). Other names in common use include (1H)-3-hydroxy-4-oxoquinoline 2,4-dioxygenase, 3-hydroxy-4-oxo-1,4-dihydroquinoline 2,4-dioxygenase, 3-hydroxy-4(1H)-one, 2,4-dioxygenase, and quinoline-3,4-diol 2,4-dioxygenase.
