Polyamine oxidase

Polyamine oxidase

In enzymology, a polyamine oxidase (EC number|1.5.3.11) is an enzyme that catalyzes the chemical reaction

:N1-acetylspermine + O2 + H2O ightleftharpoons N1-acetylspermidine + 3-aminopropanal + H2O2

The 3 substrates of this enzyme are N1-acetylspermine, O2, and H2O, whereas its 3 products are N1-acetylspermidine, 3-aminopropanal, and H2O2.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with oxygen as acceptor. The systematic name of this enzyme class is N1-acetylspermidine:oxygen oxidoreductase (deaminating). This enzyme is also called 1-N-acetylspermidine:oxygen oxidoreductase (deaminating). It has 2 cofactors: FAD, and Iron.
