Abstract
Aldehyde oxidases and xanthine dehydrogenases/oxidases belong to the m olybdenum cofactor dependent hydroxylase class of enzymes. Zymograms s how that Arabidopsis thaliana has at least three different aldehyde ox idases and one xanthine oxidase. Three different cDNA clones encoding putative aldehyde oxidases (AtAO1, 2, 3) were isolated. An aldehyde ox idase is the last step in abscisic acid (ABA) biosynthesis. AtAO1 is m ainly expressed in seeds and roots which might reflect that it is invo lved in ABA biosynthesis. (C) 1998 Elsevier Science B.V. All rights re served.
