Entry
EC 1.2.3.14                 Enzyme                                 

Name
abscisic-aldehyde oxidase;
abscisic aldehyde oxidase;
AAO3;
AOd;
AOdelta
Class
Oxidoreductases;
Acting on the aldehyde or oxo group of donors;
With oxygen as acceptor
BRITE hierarchy
Sysname
abscisic-aldehyde:oxygen oxidoreductase
Reaction(IUBMB)
abscisic aldehyde + H2O + O2 = abscisate + H2O2 [RN:R06957]
Reaction(KEGG)
Substrate
abscisic aldehyde [CPD:C13455];
H2O [CPD:C00001];
O2 [CPD:C00007]
Product
abscisate [CPD:C06082];
H2O2 [CPD:C00027]
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].
