CC   -!- FUNCTION: This enzyme catalyzes three distinct methylation reactions
CC       for converting phosphatidylethanolamine to phosphatidylcholine.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 1,2-diacyl-sn-glycero-3-phosphoethanolamine + S-adenosyl-L-
CC         methionine = 1,2-diacyl-sn-glycero-3-phospho-N-methylethanolamine +
CC         H(+) + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:11164,
