Indol-3-acetaldehid oksidaza (EC 1.2.3.7, indolacetaldehidna oksidaza, IAAld oksidaza, AO1, indol-3-acetaldehid:kiseonik oksidoreduktaza) je enzim sa sistematskim imenom (indol-3-il)acetaldehid:kiseonik oksidoreduktaza.[1][2][3][4][5][6][7] Ovaj enzim katalizuje sledeću hemijsku reakciju
- (indol-3-il)acetaldehid +H2O + O2 (indol-3-il)acetat +H2O2
Ovaj enzim je hemoprotein. On je izoforma aldehid oksidaze (EC 1.2.3.1). On ima preferenciju za aldehide sa indolnim prstenom. Smatra se da on učestvuje u biosintezi biljnih hormona, jer je njegova aktivnost veća kod mutanata koji prekomerno formiraju auksin, u odnosu na divlji tip Arabidopsis thaliana. Dok je (indol-3-il)acetaldehid preferentni supstrat, ovaj enzim takođe oksiduje indol-3-karbaldehid i acetaldehid, mada sporo. Enzim iz kukuruza sadrži FAD, gvožđe i molibden.
