General annotation (Comments)

Function

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 activity

N(1)-acetylspermine + O(2) + H(2)O = N(1)-acetylspermidine + 3-aminopropanal + H(2)O(2).

Cofactor

FAD.

Sequence similarities

Belongs to the flavin monoamine oxidase family.
