Spermine is a substrate of lentil seedling amine oxidase and is oxidized at terminal amino groups to a dialdehyde: 2 mol of hydrogen peroxide and two mol of ammonia per mol of spermine are formed. In the presence of hight amounts of spermine, the aldehydic groups formed upon oxidation of spermine by the enzyme, may react with primary amino groups of free spermine leading to the formation of aromatic pyrimidinic ring after beta-elimination at secondary amino groups.

Abstract
Spermine is a substrate of lentil seedling amine oxidase and is oxidized at terminal amino groups to a dialdehyde: 2 mol of hydrogen peroxide and two mol of ammonia per mol of spermine are formed. In the presence of hight amounts of spermine, the aldehydic groups formed upon oxidation of spermine by the enzyme, may react with primary amino groups of free spermine leading to the formation of aromatic pyrimidinic ring after beta-elimination at secondary amino groups.
