CC -!- FUNCTION: Catalyzes the three sequential steps of the methylation
CC pathway for the biosynthesis of phosphatidylcholine, a critical and
CC essential component for membrane structure. Uses S-adenosylmethionine
CC (S-adenosyl-L-methionine, SAM or AdoMet) as the methyl group donor for
CC the methylation of phosphatidylethanolamine (1,2-diacyl-sn-glycero-3-
CC phosphoethanolamine, PE) to phosphatidylmonomethylethanolamine (1,2-
CC diacyl-sn-glycero-3-phospho-N-methylethanolamine, PMME), PMME to
CC phosphatidyldimethylethanolamine (1,2-diacyl-sn-glycero-3-phospho-N,N-
CC dimethylethanolamine, PDME), and PDME to phosphatidylcholine (1,2-
CC diacyl-sn-glycero-3-phosphocholine, PC), producing S-adenosyl-L-
CC homocysteine in each step. {ECO:0000256|HAMAP-Rule:MF_03216}.
