Function
Polyamine oxidases (PAOs) are FAD-dependent enzymes involved in polyamine (PA) catabolism. In plants, the major PAs are the diamine, putrescine (Put), triamine, spermidine (Spd), tetrraamines, spermine (Spm) and thermospermine (T-Spm). These aliphatic amines of small molecular mass are involved in various biological processes, as growth factors, they play important roles in plant development, sex differentiation, fruit ripening, senility and adversity adapting. In plants, the concentrations of all the PAs are regulated by a dynamic balance between biosynthesis and catabolism. In the latter process, two kinds of enzymes are involved: a copper-dependent diamine oxidase and a flavine adenine dinucleotide (FAD)-dependent polyamine oxidases (PAOs). Recent studies revealed that PAOs are not only active in the terminal catabolism but also in a polyamine back-conversion pathway. Rice plant appears to contain two types of PAO enzymes: one functioning as a back-conversion enzyme, and the other as a terminal catabolism enzyme. It has been demonstrated that OsPAO1, as well as OsPAO3, OsPAO4 and OsPAO5, can catalyze the back-conversion reactions of some PAs. At different pH, T-Spm, Spm or other PAs can be chosen as the preferred substrate of OsPAO1; both these substrates will be converted to Spd but no further to Put.
