ENTRY       EC 2.1.1.71
NAME        Phosphatidyl-N-methylethanolamine N-methyltransferase
CLASS       Transferases
            Transferring one-carbon groups
            Methyltransferases
SYSNAME     S-Adenosyl-L-methionine:phosphatidyl-N-methylethanolamine
            $ N-methyltransferase
REACTION    S-Adenosyl-L-methionine + Phosphatidyl-N-methylethanolamine =
            S-Adenosyl-L-homocysteine + Phosphatidyl-N-dimethylethanolamine
SUBSTRATE   S-Adenosyl-L-methionine
            Phosphatidyl-N-methylethanolamine
PRODUCT     S-Adenosyl-L-homocysteine
            Phosphatidyl-N-dimethylethanolamine
COMMENT     The enzyme also catalyses the transfer of a further methyl group,
            producing phosphatidylcholine.
