Choline-phosphate cytidylyltransferase A
Choline/ethanolaminephosphotransferase 1
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
Phosphatidylserine decarboxylase proenzyme
Ethanolamine-phosphate cytidylyltransferase
CDP-Choline + DG(18:1(11Z)/18:0/0:0) → Cytidine monophosphate + Hydrogen Ion + PC(18:1(11Z)/18:0)
Phosphatidylcholine Biosynthesis PC(18:1(11Z)/18:0)
CDP-ethanolamine + DG(18:1(11Z)/18:0/0:0) → Cytidine monophosphate + PE(18:1(11Z)/18:0)
PE-NMe2(18:1(11Z)/18:0) + S-Adenosylmethionine → PC(18:1(11Z)/18:0) + S-Adenosylhomocysteine
PE-NMe(18:1(11Z)/18:0) + S-Adenosylmethionine → PE-NMe2(18:1(11Z)/18:0) + S-Adenosylhomocysteine
PE(18:1(11Z)/18:0) + S-Adenosylmethionine → PE-NMe(18:1(11Z)/18:0) + S-Adenosylhomocysteine
