As the products of the reaction cannot be converted directly to other polyamines, this class of polyamine oxidases is considered to be involved in the terminal catabolism of polyamines [1]. This enzyme less efficiently catalyses the oxidation of N1-acetylspermine and spermine. A flavoprotein (FAD). Differs in specificity from EC
1.5.3.13 (N1-acetylpolyamine oxidase), EC
1.5.3.15 [N8-acetylspermidine oxidase (propane-1,3-diamine-forming)], EC
1.5.3.16 (spermine oxidase) and EC
1.5.3.17 (non-specific polyamine oxidase).
