EC 1.5.3.17     
Accepted name: non-specific polyamine oxidase
Reaction: (1) spermine + O2 + H2O = spermidine + 3-aminopropanal + H2O2
(2) spermidine + O2 + H2O = putrescine + 3-aminopropanal + H2O2
(3) N1-acetylspermine + O2 + H2O = spermidine + 3-acetamidopropanal + H2O2
(4) N1-acetylspermidine + O2 + H2O = putrescine + 3-acetamidopropanal + H2O2
Other name(s): polyamine oxidase (ambiguous); Fms1; AtPAO3
Systematic name: polyamine:oxygen oxidoreductase (3-aminopropanal or 3-acetamidopropanal-forming)
Comments: A flavoprotein (FAD). The non-specific polyamine oxidases may differ from each other considerably. The enzyme from Saccharomyces cerevisiae shows a rather broad specificity and also oxidizes N8-acetylspermidine [3]. The enzyme from Ascaris suum shows high activity with spermine and spermidine, but also oxidizes norspermine [2]. The enzyme from Arabidopsis thaliana shows high activity with spermidine, but also oxidizes other polyamines [1]. The specific polyamine oxidases are classified as EC 1.5.3.13 (N1-acetylpolyamine oxidase), EC 1.5.3.14 (polyamine oxidase (propane-1,3-diamine-forming)), EC 1.5.3.15 (N8-acetylspermidine oxidase (propane-1,3-diamine-forming)) and EC 1.5.3.16 (spermine oxidase).
