Putrescine N-methyltransferase (PMT; EC. 2.5.1.53) catalyzes the S-adenosylmethionine-dependent N-methylation of putrescine to form N-methylputrescine, which was the first committed step in tropane alkaloid biosynthetic pathway. Two PMT cDNA clones [Anisodus acutangulus putrescine N-methyltransferase 1 (AaPMT1), GenBank Accession No. EU670745; AaPMT2, GenBank Accession No. EU670746] were obtained and characterized together from Anisodus acutangulus for the first time. The full-length cDNA of… CONTINUE READING
