Choline-phosphate cytidylyltransferase A
Choline/ethanolaminephosphotransferase 1
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
Phosphatidylserine decarboxylase proenzyme
Ethanolamine-phosphate cytidylyltransferase
Phosphatidylethanolamine N-methyltransferase
PE(20:1(11Z)/20:3(5Z,8Z,11Z)) + S-Adenosylmethionine → PE-NMe(20:1(11Z)/20:3(5Z,8Z,11Z)) + S-Adenosylhomocysteine
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
PE-NMe(20:1(11Z)/20:3(5Z,8Z,11Z)) + S-Adenosylmethionine → PE-NMe2(20:1(11Z)/20:3(5Z,8Z,11Z)) + S-Adenosylhomocysteine
PE-NMe2(20:1(11Z)/20:3(5Z,8Z,11Z)) + S-Adenosylmethionine → PC(20:1(11Z)/20:3(5Z,8Z,11Z)) + S-Adenosylhomocysteine
Cytidine triphosphate + Phosphorylcholine → CDP-Choline + Pyrophosphate
CDP-Choline + DG(20:1(11Z)/20:3(5Z,8Z,11Z)/0:0) → Cytidine monophosphate + Hydrogen Ion + PC(20:1(11Z)/20:3(5Z,8Z,11Z))
Adenosine triphosphate + Choline → Adenosine diphosphate + Phosphorylcholine
