Choline/ethanolaminephosphotransferase 1
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
CDP-ethanolamine + DG(24:1(15Z)/18:1(9Z)/0:0) → Cytidine monophosphate + PE(24:1(15Z)/18:1(9Z))
Phosphatidylserine decarboxylase proenzyme
Phosphatidylethanolamine Biosynthesis PE(24:1(15Z)/18:1(9Z))
Ethanolamine-phosphate cytidylyltransferase
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
