1.13.11.47	1H-3-hydroxy-4-oxoquinaldine + O2	HOD possesses a classical alpha/beta-hydrolase fold core domain additionally equipped with a cap domain. Organic substrates bind in a preorganized active site with an orientation ideally suited for 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, typically employed to stabilize the tetrahedral intermediate in ester hydrolysis reactions, is utilized here to host and control oxygen chemistry, which is proposed to involve a peroxide anion intermediate. Product release by proton back transfer from the catalytic histidine is driven by minimization of intramolecular charge repulsion. Structural and kinetic data suggest a nonnucleophilic general-base mechanism	Paenarthrobacter nitroguajacolicus	N-acetylanthranilic acid + CO	-	?	186663
