Choline/ethanolaminephosphotransferase 1
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
Phosphatidylethanolamine Biosynthesis PE(20:0/22:2(13Z,16Z))
Phosphatidylserine decarboxylase proenzyme
Ethanolamine-phosphate cytidylyltransferase
CDP-ethanolamine + DG(20:0/22:2(13Z,16Z)/0:0) → Cytidine monophosphate + PE(20:0/22:2(13Z,16Z))
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
