Polyamine oxidase (PAO) catalyzes the conversion of N-acetylspermine, molecular oxygen and water to N-acetylspermidine, 3-aminopropanol and hydrogen peroxide. PAO via its production of hydrogen peroxide, is one of the key elements for oxidative burst which induces programmed cell death. PAO is involved in polyamine catabolism and uses FAD as a cofactor.


1yy5, 1rsg, 1xpq – yPAO – yeast
3kpf – yPAO (mutant)
1b37, 1b5q, 1h81 – mPAO FAD-binding domain – maize

Polyamine oxidase binary complex

1h82, 1h83, 1h84, 1h86 – mPAO FAD-binding domain + polyamine
1z6l - yPAO + polyamine
