ID 1.2.3.7 DE indole-3-acetaldehyde oxidase. AN IAAld oxidase. AN IAA oxidase. AN indoleacetaldehyde oxidase. CA H2O + indole-3-acetaldehyde + O2 = (indol-3-yl)acetate + H(+) + H2O2. CC -!- Isoform of EC 1.2.3.1. CC -!- Has a preference for aldehydes having an indole-ring structure as CC substrate. CC -!- May play a role in plant hormone biosynthesis as its activity is CC higher in the auxin-overproducing mutant, super-root1, than in wild- CC type Arabidopsis thaliana. CC -!- While (indol-3-yl)acetaldehyde is the preferred substrate, it also CC oxidizes indole-3-carbaldehyde and acetaldehyde, but more slowly.
