ID 1.2.3.14 DE Abscisic-aldehyde oxidase. AN AO-delta. CA Abscisic aldehyde + H(2)O + O(2) = abscisate + H(2)O(2). CC -!- Acts on both (+)- and (-)-abscisic aldehyde. CC -!- Involved in the abscisic-acid biosynthesis pathway in plants, along CC with EC 1.1.1.288, EC 1.13.11.51 and EC 1.14.13.93. CC -!- While abscisic aldehyde is the best substrate, the enzyme also acts CC with indole-3-aldehyde, 1-naphthaldehyde and benzaldehyde as CC substrates, but more slowly. DR Q7G9P4, ALDO3_ARATH; //
