Accepted Name
Aldehyde oxidase.
Alternative Name(s)
Quinoline oxidase.

Comment(s)
  • The enzyme from liver exhibits a broad substrate specificity, and is involved in the metabolism of xenobiotics, including the oxidation of N-heterocycles and aldehydes and the reduction of N-oxides, nitrosamines, hydroxamic acids, azo dyes, nitropolycyclic aromatic hydrocarbons, and sulfoxides.
  • The enzyme is also responsible for the oxidation of retinal, an activity that was initially attributed to a distinct enzyme (EC 1.2.3.11).
  • Formerly EC 1.2.3.11.
