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 (Probable) (PubMed:8344945).
CC       Uses S-adenosylmethionine (S-adenosyl-L-methionine, SAM or AdoMet) as
CC       the methyl group donor for the methylation of phosphatidylethanolamine
CC       (1,2-diacyl-sn-glycero-3-phosphoethanolamine, PE) to
CC       phosphatidylmonomethylethanolamine (1,2-diacyl-sn-glycero-3-phospho-N-
CC       methylethanolamine, PMME), PMME to phosphatidyldimethylethanolamine
CC       (1,2-diacyl-sn-glycero-3-phospho-N,N-dimethylethanolamine, PDME), and
CC       PDME to phosphatidylcholine (1,2-diacyl-sn-glycero-3-phosphocholine,
CC       PC), producing S-adenosyl-L-homocysteine in each step (Probable)
