Enzyme Commission Primary Name: polyamine oxidase (propane-1,3-diamine-forming)

Enzyme Commission Synonyms: MPAO, maize PAO

Standard Gibbs Free Energy (ΔrG in kcal/mol): -22.204773 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
A flavoprotein (FAD). This enzyme, found in the cell walls of monocot plants, oxidizes spermine and spermidine at the four-carbon side of their secondary amine, forming propane-1,3-diamine and hydrogen peroxide [Tavladoraki98]. As the products cannot be converted directly to other polyamines, this class of polyamine oxidases is considered to be involved in the terminal catabolism of polyamines. The enzyme also accepts N1-acetylspermine as substrate, but is quickly inactivated during the reaction [Sebela01].
