Choline/ethanolaminephosphotransferase 1
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
Phosphatidylserine decarboxylase proenzyme
Ethanolamine-phosphate cytidylyltransferase
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
Phosphatidylethanolamine Biosynthesis PE(18:0/18:1(9Z))
CDP-ethanolamine + DG(18:0/18:1(9Z)/0:0) → Cytidine monophosphate + PE(18:0/18:1(9Z))
