Putrescine N-methyltransferase
Template:Short description Template:Infobox enzyme In enzymology, a putrescine N-methyltransferase (EC 2.1.1.53) is an enzyme that catalyzes the chemical reaction
- S-adenosyl-L-methionine + putrescine S-adenosyl-L-homocysteine + N-methylputrescine
Thus, the two substrates of this enzyme are S-adenosyl methionine and putrescine, whereas its two products are S-adenosylhomocysteine and N-methylputrescine.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. 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]
