Putrescine N-Methyltransferase in Cultured Roots of Hyoscyamus albus: Butylamine as a Potent Inhibitor of the Transferase both in Vitro and in Vivo
Biosynthesis of tropane alkaloids is thought to proceed by way of the diamine putrescine, followed by its methylation by putrescine N -methyltransferase (PMT; EC 2.1.1.53). High PMT activities were found in branch roots and/or cultured roots of several solanaceous plants. PMT was partially purified...
