N8 acetylspermidine oxidase (propane 1,3 diamine forming)

N⁸-acetylspermidine oxidase (propane-1,3-diamine-forming) (EC 1.5.3.15) is an enzyme with systematic name N⁸-acetylspermidine:oxygen oxidoreductase (propane-1,3-diamine-forming). This enzyme catalyses the following chemical reaction

N⁸-acetylspermidine + O₂ + H₂O ⇌ propane-1,3-diamine + 4-acetamidobutanal + H₂O₂

This enzyme is also active n N¹-acetylspermine, and it has weak activity on N¹,N¹²-diacetylspermine.
