ID   1.13.11.48
DE   3-hydroxy-2-methylquinolin-4-one 2,4-dioxygenase.
AN   (1H)-3-hydroxy-4-oxoquinaldine 2,4-dioxygenase.
CA   3-hydroxy-2-methyl-1H-quinolin-4-one + O2 = CO + H(+) +
CA   N-acetylanthranilate.
CC   -!- Does not contain a metal center or organic cofactor.
CC   -!- Fission of two C-C bonds: 2,4-dioxygenolytic cleavage with
CC       concomitant release of carbon monoxide.
CC   -!- The enzyme from Arthrobacter sp. can also act on 3-hydroxy-4-
CC       oxoquinoline, forming N-formylanthranilate and CO (cf.
CC       EC 1.13.11.47), but more slowly.
