Abstract

The biosynthesis of certain amines in Lathyrus sativus seedlings was studied in isolated shoots and cotyledons. In shoots, arginine was about 14 times more efficient than ornithine for the synthesis of agmatine, putrescine, spermidine and spermine. Isotope dilution experiments, and the changes in specific activities of the 4 amines with time when 14C-arginine served as the precursor, indicated that putrescine and the polyamines were formed mainly from arginine, via agmatine. Similar experiments showed that cadaverine was formed at least in part from homoarginine, though lysine was ca 4 times more effective as a precursor. The pattern of changes in specific activity of homoagmatine and cadaverine with time when 14C-homoarginine served as the precursor support the conclusion that homoarginine and arginine follow analogous metabolic routes in the biosynthesis of putrescine and cadaverine respectively.
