ID 1.2.3.1 DE aldehyde oxidase. AN quinoline oxidase. AN retinal oxidase. CA an aldehyde + H2O + O2 = a carboxylate + H(+) + H2O2. CC -!- The enzyme from liver exhibits a broad substrate specificity, and is CC involved in the metabolism of xenobiotics, including the oxidation of CC N-heterocycles and aldehydes and the reduction of N-oxides, CC nitrosamines, hydroxamic acids, azo dyes, nitropolycyclic aromatic CC hydrocarbons, and sulfoxides. CC -!- The enzyme is also responsible for the oxidation of retinal, CC an activity that was initially attributed to a distinct enzyme CC (EC 1.2.3.11). CC -!- Formerly EC 1.2.3.11.
