Enzyme Information

3-hydroxy-2-methylquinolin-4-one 2,4-dioxygenase.
based on mapping to UniProt O31266
3-hydroxy-2-methyl-1H-quinolin-4-one + O(2) = N-acetylanthranilate + CO.
-!- Does not contain a metal center or organic cofactor. -!- Fission of two C-C bonds: 2,4-dioxygenolytic cleavage with concomitant release of carbon monoxide. -!- The enzyme from Arthrobacter sp. can also act on 3-hydroxy-4- oxoquinoline, forming N-formylanthranilate and CO (cf. EC 1.13.11.47), but more slowly.
