Protein attributes

Sequence length	1337 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Catalytic activity	An aldehyde + H(2)O + O(2) = a carboxylic acid + H(2)O(2).
Cofactor	Binds 2 2Fe-2S clusters By similarity. FAD By similarity. Molybdopterin By similarity.
Subunit structure	Aldehyde oxidases (AO) are homo- and heterodimers of AO subunits By similarity.
Tissue specificity	Transcripts expressed at high levels in developing siliques and at low levels in dry seeds.
Induction	Induced by dehydration, in rosette but not in roots.
Miscellaneous	Plants lacking AAO4 have normal abscisic acid (ABA) levels, normal germination and are not affected in abscisic aldehyde oxidase activity in siliques, dry seeds and leaves.
Sequence similarities	Belongs to the xanthine dehydrogenase family. Contains 1 2Fe-2S ferredoxin-type domain. Contains 1 FAD-binding PCMH-type domain.
Sequence caution	The sequence AAB80640.1 differs from that shown. Reason: Erroneous gene model prediction.
