Polyamine oxidase in rat tissues

Biochimica Et Biophysica Acta - Biomembranes, 1980
An assay procedure for polyamine oxidase in tissue homogenates was devised. The method is based on the degradation of N1,n12-diacetylspermine to N1-acetylspermidine and the determination using TLC of the latter. Polyamine oxidase activity is high in most tissues. Its activity is comparable to that of spermidine and spermine synthase.

Metabolism of acetylpolyamines by monoamine oxidase, diamine oxidase and polyamine oxidase

Biochimica Et Biophysica Acta - General Subjects, 1981
N1-Monoacetylspermine, N1,N12-diacetylspermine and N1-monoacetylspermidine were found to be good substrates for rat liver polyamine oxidase, but not for rat liver mitochondrial monoamine oxidase. N8-Monoacetylspermidine, monoacetylcadaverine, monoacetylputrescine and monoacetyl-1,3-diaminopropane were oxidized by the monoamine oxidase when the ...

In vitro and in vivo inhibition of plant polyamine oxidase activity by polyamine analogues

Phytochemistry, 2008
Polyamine oxidase from Avena sativa L. cv. Cristal seedlings was purified to homogeneity using a simple four-step purification protocol including an infiltration washing technique. The enzyme had a high affinity for spermidine and spermine (K(m) approximately 5.5 and 1.2 microM, respectively), and also oxidized norspermidine (K(m) approximately 64.0 ...
