In enzymology, a phosphatidyl-N-methylethanolamine N-methyltransferase (EC 2.1.1.71) is an enzyme that catalyzes the chemical reaction Thus, 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.
The systematic name of this enzyme class is S-adenosyl-L-methionine:phosphatidyl-N-methylethanolamine N-methyltransferase.
This enzyme participates in glycine, serine and threonine metabolism and glycerophospholipid metabolism.
