Phosphatidylserine decarboxylase proenzyme, mitochondrial
Ethanolamine-phosphate cytidylyltransferase
Phosphatidylethanolamine Biosynthesis PE(22:1(13Z)/18:1(9Z))
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
CDP-ethanolamine + DG(22:1(13Z)/18:1(9Z)/0:0) → Cytidine monophosphate + PE(22:1(13Z)/18:1(9Z))
