, a 3-hydroxy-4-oxoquinoline 2,4-dioxygenase
is an enzyme
the chemical reaction
- 3-hydroxy-1H-quinolin-4-one + O2 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.
