Enzyme Commission Summary:
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 [Landry03]. The enzyme from Ascaris suum shows high activity with spermine and spermidine, but also oxidizes norspermine [Muller92b]. The enzyme from Arabidopsis thaliana shows high activity with spermidine, but also oxidizes other polyamines [Moschou08]. The specific polyamine oxidases are classified as EC 184.108.40.206 (N1-acetylpolyamine oxidase), EC 220.127.116.11 (polyamine oxidase (propane-1,3-diamine-forming)), EC 18.104.22.168 (N8-acetylspermidine oxidase (propane-1,3-diamine-forming)) and EC 22.214.171.124 (spermine oxidase).
