Choline/ethanolaminephosphotransferase 1
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
Phosphatidylserine decarboxylase proenzyme
Ethanolamine-phosphate cytidylyltransferase
Phosphatidylethanolamine Biosynthesis PE(18:1(11Z)/20:1(11Z))
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
CDP-ethanolamine + DG(18:1(11Z)/20:1(11Z)/0:0) → Cytidine monophosphate + PE(18:1(11Z)/20:1(11Z))
