The systematic name of this enzyme class is S-adenosyl-L-methionine:putrescine N-methyltransferase. This enzyme is also called putrescine methyltransferase.  This enzyme participates in alkaloid biosynthesis ii.This enzyme is important in the synthesis of many plant alkaloids.[1] It evolved from spermidine synthase.[2]References[edit]^ Biastoff S, Brandt W, Dr\u00e4ger B (2009-10-01). “Putrescine N-methyltransferase–the start for alkaloids”.
