• Germination of soybean seeds is accompanied by a rapid increase in amine oxidase activity in the root and hypocotyl but not in the cotyledons. The partially purified enzyme from cotyledonless specimens readily oxidizes cadaverine, putrescine, spermidine and agmatine, while spermine, L-lysine and D-lysine are oxidized more slowly. Inhibition experiments showed that carbonyl and heavy metal chelating reagents are effective inhibitors of soybean amine oxidase. The diethyldithiocarbamate-treated enzyme was reactivated specifically by cupric copper. These results suggest that the amine oxidase in soybean seedlings should be regarded as a diamine oxidase (E.C. 1 .4.3.6).
