phenylhydrazine/phaseolus vulgaris

In tropical legumes like French bean (Phaseolus vulgaris) or soybean (Glycine max), most of the atmospheric nitrogen fixed in nodules is used for synthesis of the ureides allantoin and allantoic acid, the major long distance transport forms of organic nitrogen in these species. The purpose of this

Ureidoglycolate is an intermediate in the degradation of the ureides, allantoin and allantoate, found in many organisms. In some leguminous plant species these compounds are used to transport recently fixed nitrogen in the root nodules to the aerial parts of the plant. In the present study, it was

Allantoate degradation was demonstrated in the extracts of ungerminated seeds and roots, stems and leaves in germinated seedlings of French bean (Phaseolus vulgaris L.). Activity of allantoate-degrading enzyme could only be measured when phenylhydrazine was included in the assay mixture. Partial
