CC -!- FUNCTION: Catalyzes the second two steps of the methylation pathway of
CC phosphatidylcholine biosynthesis, the SAM-dependent methylation of
CC phosphatidylmonomethylethanolamine (PMME) to
CC phosphatidyldimethylethanolamine (PDME) and of PDME to
CC phosphatidylcholine (PC). {ECO:0000256|HAMAP-Rule:MF_03216}.
