Accepted name: phosphatidyl-N-methylethanolamine N-methyltransferase
Reaction: S-adenosyl-L-methionine + phosphatidyl-N-methylethanolamine = S-adenosyl-L-homocysteine + phosphatidyl-N-dimethylethanolamine
Other name(s): phosphatidylmonomethylethanolamine methyltransferase; methyltransferase II; phospholipid methyltransferase; PLMT; phosphatidyl-N-methylethanolamine methyltransferase; phosphatidyl-N-monomethylethanolamine methyltransferase; phosphatidylethanolamine methyltransferase I; phosphatidylmonomethylethanolamine methyltransferase
Systematic name: S-adenosyl-L-methionine:phosphatidyl-N-methylethanolamine N-methyltransferase
Comments: The enzyme also catalyses the transfer of a further methyl group, producing phosphatidylcholine.
