In enzymology, an ethanolaminephosphotransferase (EC 2.7.8.1) is an enzyme that catalyzes the chemical reaction
- CDP-ethanolamine + 1,2-diacylglycerol [math]\displaystyle{ \rightleftharpoons }[/math] CMP + a phosphatidylethanolamine
Thus, the two substrates of this enzyme are CDP-ethanolamine and 1,2-diacylglycerol, whereas its two products are CMP and phosphatidylethanolamine.
This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups. The systematic name of this enzyme class is CDP-ethanolamine:1,2-diacylglycerol ethanolaminephosphotransferase. Other names in common use include EPT, diacylglycerol ethanolaminephosphotransferase, CDPethanolamine diglyceride phosphotransferase, and phosphorylethanolamine-glyceride transferase. This enzyme participates in 3 metabolic pathways: aminophosphonate metabolism, glycerophospholipid metabolism, and ether lipid metabolism.
