Phosphatidylserine decarboxylase proenzyme, mitochondrial
Ethanolamine-phosphate cytidylyltransferase
Phosphatidylethanolamine Biosynthesis PE(20:4(8Z,11Z,14Z,17Z)/18:2(9Z,12Z))
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
