IntEnz Enzyme Nomenclature


Accepted name:
non-specific polyamine oxidase
Other names:
polyamine oxidase [ambiguous]
Systematic name:
polyamine:oxygen oxidoreductase (3-aminopropanal or 3-acetamidopropanal-forming)




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 (N1-acetylpolyamine oxidase), EC (polyamine oxidase (propane-1,3-diamine-forming)), EC (N8-acetylspermidine oxidase (propane-1,3-diamine-forming)) and EC (spermine oxidase).
