CC -!- FUNCTION: Catalyzes the first step of the methylation pathway of
CC phosphatidylcholine biosynthesis, the SAM-dependent methylation of
CC phosphatidylethanolamine (PE) to phosphatidylmonomethylethanolamine
CC (PMME). {ECO:0000255|HAMAP-Rule:MF_03217}.
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,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:64573, ChEBI:CHEBI:64612; EC=2.1.1.17;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03217};
CC -!- PATHWAY: Phospholipid metabolism; phosphatidylcholine biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_03217}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000255|HAMAP-Rule:MF_03217}; Multi-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_03217}.
CC -!- SIMILARITY: Belongs to the class VI-like SAM-binding methyltransferase
CC superfamily. CHO2 family. {ECO:0000255|HAMAP-Rule:MF_03217}.
