Thus the bulk of the Formosan flora was derived from China or from other floras t...

S-Adenosyl-l-methionine:tetrahydroprotoberberine cis-N-methyltransferase (EC 2.1.1.122) catalyzes the conversion of (S)-stylopine to the quaternary ammonium alkaloid, (S)-cis-N-methylstylopine, as a key step in the biosynthesis of protopine and benzophenanthridine alkaloids in plants. A full-length cDNA encoding a protein exhibiting 45 and 48% amino acid identity with coclaurine N-methyltransfe...
