• The oxidation of spermidine and spermine by the partially purified amine oxidase of beef serum was examined. Under the present conditions, when spermidine was used as substrate, 1 mole each of ammonia and hydrogen peroxide were formed consuming 1 mole of oxygen. By contrast, in the case of spermine 2 moles each of ammonia and hydrogen peroxide were formed consuming 2 moles of oxygen. At the end of reaction, amino groups assayed in the reaction products of the two polyamines were found to be 2 moles equivalent of primary amino groups per 1 mole of the substrates. Another finding was that putrescine was identified and determined in the end products. The presence of an unidentified amino aldehyde in the end products was suggested using the resorcinol reagent which yield a fluorescent compound with the amino aldehyde. From these observations, possible pathways of the oxidative degradation of spermidine and spermine by the said enzyme were discussed.
