ID   1.5.3.17
DE   non-specific polyamine oxidase.
AN   polyamine oxidase.
CA   (1) spermine + O2 + H2O = 3-aminopropanal + spermidine + H2O2.
CA   (2) spermidine + O2 + H2O = 3-aminopropanal + putrescine + H2O2.
CA   (3) N(1)-acetylspermine + O2 + H2O = 3-acetamidopropanal + spermidine +
CA   H2O2.
CA   (4) N(1)-acetylspermidine + O2 + H2O = 3-acetamidopropanal + putrescine +
CA   H2O2.
CC   -!- The non-specific polyamine oxidases may differ from each other
CC       considerably.
CC   -!- The enzyme from Saccharomyces cerevisiae shows a rather broad
CC       specificity and also oxidizes N(8)-acetylspermidine.
CC   -!- The enzyme from Ascaris suum shows high activity with spermine and
CC       spermidine, but also oxidizes norspermine.
CC   -!- The enzyme from Arabidopsis thaliana shows high activity with
CC       spermidine, but also oxidizes other polyamines.
CC   -!- The specific polyamine oxidases are classified as EC 1.5.3.13,
CC       EC 1.5.3.14, EC 1.5.3.15 and EC 1.5.3.16.
CC   -!- Formerly EC 1.5.3.11.
