In enzymology a phosphatidyl-N-methylethanolamine N-methyltransferase (EC 2.1.1.71) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + phosphatidyl-N-methylethanolamine S-adenosyl-L-homocysteine + phosphatidyl-N-dimethylethanolamineThus the two substrates of this enzyme are S-adenosyl methionine and phosphatidyl-N-methylethanolamine whereas its two products are S-adenosylhomocysteine and phosphatidyl-N-dimethylethanolamine.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
