ENZYME entry: EC 1.5.3.14

Accepted Name
polyamine oxidase (propane-1,3-diamine-forming).
Alternative Name(s)
maize PAO.
MPAO.
Reaction catalysed
H2O + O2 + spermidine <=> 4-aminobutanal + H2O2 + propane-1,3-diamine
Comment(s)
  • 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.
  • Catalyzes less efficiently the oxidation of N(1)-acetylspermine and spermine.
  • Differs in specificity from EC 1.5.3.13, EC 1.5.3.15, EC 1.5.3.16 and EC 1.5.3.17.
  • Formerly EC 1.5.3.11, EC 1.5.3.n6, EC 1.5.3.n7, EC 1.5.3.n8 and EC 1.5.3.n9.
