In enzymology, a phosphatidyl-N-methylethanolamine N-methyltransferase is an enzyme that catalyzes the chemical reaction
S-adenosyl-L-methionine + phosphatidyl-N-methylethanolamine
\rightleftharpoons
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. Other names in common use include phosphatidylmonomethylethanolamine methyltransferase, methyltransferase II, phospholipid methyltransferase, PLMT, phosphatidyl-N-methylethanolamine methyltransferase, phosphatidyl-N-monomethylethanolamine methyltransferase, phosphatidylethanolamine methyltransferase I, and phosphatidylmonomethylethanolamine methyltransferase. This enzyme participates in glycine, serine and threonine metabolism and glycerophospholipid metabolism.
