Comments

FUNCTION: Flavoenzyme which catalyzes the oxidation of N(1)-acetylspermine to spermidine and is thus involved in the polyamine back-conversion. Can also oxidize N(1)-acetylspermidine to putrescine. Substrate specificity: N(1)-acetylspermine = N(1)-acetylspermidine > N(1),N(12)-diacylspermine >> spermine. Does not oxidize spermidine. Plays an important role in the regulation of polyamine intracellular concentration and has the potential to act as a determinant of cellular sensitivity to the antitumor polyamine analogs.
CATALYTIC ACTIVITY: N¹-acetylspermine + O₂ + H₂O = N¹-acetylspermidine + 3-aminopropanal + H₂O₂.
COFACTOR: FAD (By similarity).
PATHWAY: Amine and polyamine metabolism; spermine metabolism .
SUBUNIT: Monomer (By similarity).
SUBCELLULAR LOCATION: Peroxisome (By similarity). Cytoplasm (By similarity).

ALTERNATIVE PRODUCTS: 11 named isoforms [FASTA] produced by alternative splicing.

TISSUE SPECIFICITY: Widely expressed. Not detected in spleen. Expressed at lower level in neoplastic tissues.
INDUCTION: By polyamine analogs.
MISCELLANEOUS: Oxidizes N(1)-acetylated polyamines on the exo-side of their N(4)-amino groups. Plant PAO oxidizes spermine on the endo-side of the N(4)-nitrogen (By similarity).
SIMILARITY: Belongs to the flavin monoamine oxidase family.
