EC 1.2.3.14 Details
EC number
1.2.3.14
Accepted name
abscisic-aldehyde oxidase
Reaction
abscisic aldehyde + H2O + O2 = abscisate + H2O2
Other name(s)
abscisic aldehyde oxidase, AAO3, AOd, AOδ
Systematic name
abscisic-aldehyde:oxygen oxidoreductase
CAS registry number
129204-36-0
Comment
Acts on both (+)- and (-)-abscisic aldehyde. Involved in the abscisic-acid biosynthesis pathway in plants, along with EC 1.1.1.288, (xanthoxin dehydrogenase), EC 1.13.11.51 (9-cis-epoxycarotenoid dioxygenase) and EC 1.14.13.93 [(+)-abscisic acid 8′-hydroxylase]. While abscisic aldehyde is the best substrate, the enzyme also acts with indole-3-aldehyde, 1-naphthaldehyde and benzaldehyde as substrates, but more slowly [3].
