FunFam 6: Aldehyde oxidase

There are 3 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
Indole-3-acetaldehyde oxidase. [EC: 1.2.3.7]
(Indol-3-yl)acetaldehyde + H(2)O + O(2) = (indol-3-yl)acetate + H(2)O(2).
  • Isoform of EC 1.2.3.1.
  • Has a preference for aldehydes having an indole-ring structure as substrate.
  • May play a role in plant hormone biosynthesis as its activity is higher in the auxin-overproducing mutant, super-root1, than in wild- type Arabidopsis thaliana.
  • While (indol-3-yl)acetaldehyde is the preferred substrate, it also oxidizes indole-3-carbaldehyde and acetaldehyde, but more slowly.

Aldehyde oxidase. [EC: 1.2.3.1]
An aldehyde + H(2)O + O(2) = a carboxylate + H(2)O(2).
  • 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.

Abscisic-aldehyde oxidase. [EC: 1.2.3.14]
Abscisic aldehyde + H(2)O + O(2) = abscisate + H(2)O(2).
  • Acts on both (+)- and (-)-abscisic aldehyde.
  • Involved in the abscisic-acid biosynthesis pathway in plants, along with EC 1.1.1.288, EC 1.13.11.51 and EC 1.14.13.93.
  • While abscisic aldehyde is the best substrate, the enzyme also acts with indole-3-aldehyde, 1-naphthaldehyde and benzaldehyde as substrates, but more slowly.
