Spermine oxidase (EC 1.5.3.16, PAOh1/SMO, AtPAO1, AtPAO4, SMO) is an enzyme with systematic name spermidine:oxygen oxidoreductase (spermidine-forming). This enzyme catalyses the following chemical reaction

spermine + O₂ + H₂O ⇌ spermidine + 3-aminopropanal + H₂O₂

The enzyme from Arabidopsis thaliana oxidizes norspermine to norspermidine.
