1h-3-hydroxy-4-oxoquinaldine 2,4-dioxygenase (HOD) Oxygenases without requirement for cofactors or metal ions, catalyzing N-heterocyclic-ring cleavage and formation of carbon monoxide. Composed of a classical alpha/beta-hydrolase fold core domain with a cap domain. Organic substrates undergo selective deprotonation of their hydroxyl group by a His/Asp charge-relay system affording the generation of electron-donating species. The oxyanion hole of the alpha/beta-hydrolase fold, is utilized here to host and control oxygen chemistry involving a peroxide anion intermediate. Product release occurs by proton back transfer from the catalytic histidine.It is a non-nucleophilic general-base mechanism
