Catalyzes the second two steps of the methylation pathway of phosphatidylcholine biosynthesis, the SAM-dependent methylation of phosphatidylmonomethylethanolamine (PMME) to phosphatidyldimethylethanolamine (PDME) and of PDME to phosphatidylcholine (PC).
Lifibrate is an inhibitor of cholinephosphotransferase (CPT), phosphatidyl-N-methylethanolamine N-methyltransferase (PME-NMT), and phosphatidyl-N,N-dimethylethanolamine N-methyltransferase (PDE-NMT).
