Function

Function:
Catalyzes phosphatidylethanolamine biosynthesis from CDP-ethanolamine. It thereby plays a central role in the formation and maintenance of vesicular membranes. Involved in the formation of phosphatidylethanolamine via 'Kennedy' pathway.
Pathway:
Phospholipid metabolism; phosphatidylethanolamine biosynthesis; phosphatidylethanolamine from ethanolamine: step 3/3.
Catalytic Activity:
CDP-ethanolamine + 1,2-diacyl-sn-glycerol = CMP + a phosphatidylethanolamine.
Cofactor:
COFACTOR: Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
Kinetics:
BIOPHYSICOCHEMICAL PROPERTIES: Kinetic parameters: KM=1.8 uM for CDP-ethanolamine
