Organism
Zea mays (Maize)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes the oxidation of the secondary amino group of polyamines (spermine, spermidine and their acetyl derivatives). Plays an important role in the regulation of polyamine intracellular concentration.

Catalytic activityi

Spermidine + O2 + H2O = propane-1,3-diamine + 4-aminobutanal +H2O2.
N(8)-acetylspermidine + O2 + H2O = propane-1,3-diamine + 4-acetamidobutanal + H2O2.
Spermine + O2 + H2O = N-(3-aminopropyl)-4-aminobutanal + trimethylenediamine + H2O2.
N(1)-acetylspermine + O2 + H2O = N-(3-acetamidopropyl)-4-aminobutanal + trimethylenediamine + H2O2.

Cofactori

Binds 1 FAD per subunit.
