FunFam 1: 1H-3-hydroxy-4-oxoquinaldine 2,4-dioxygenase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
3-hydroxy-2-methylquinolin-4-one 2,4-dioxygenase. [EC: 1.13.11.48]
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.
