IntEnz Enzyme Nomenclature


Accepted name:
polyamine oxidase (propane-1,3-diamine-forming)
Other name:
Systematic name:
spermidine:oxygen oxidoreductase (propane-1,3-diamine-forming)




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