Choline-phosphate cytidylyltransferase A
Choline/ethanolaminephosphotransferase 1
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
PE-NMe(22:1(13Z)/22:2(13Z,16Z)) + S-Adenosylmethionine → PE-NMe2(22:1(13Z)/22:2(13Z,16Z)) + S-Adenosylhomocysteine
PE-NMe2(22:1(13Z)/22:2(13Z,16Z)) + S-Adenosylmethionine → PC(22:1(13Z)/22:2(13Z,16Z)) + S-Adenosylhomocysteine
Phosphatidylserine decarboxylase proenzyme
Ethanolamine-phosphate cytidylyltransferase
Phosphatidylethanolamine N-methyltransferase
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
Cytidine triphosphate + Phosphorylcholine → CDP-Choline + Pyrophosphate
Phosphatidylcholine Biosynthesis PC(22:1(13Z)/22:2(13Z,16Z))
Adenosine triphosphate + Choline → Adenosine diphosphate + Phosphorylcholine
CDP-Choline + DG(22:1(13Z)/22:2(13Z,16Z)/0:0) → Cytidine monophosphate + Hydrogen Ion + PC(22:1(13Z)/22:2(13Z,16Z))
PE(22:1(13Z)/22:2(13Z,16Z)) + S-Adenosylmethionine → PE-NMe(22:1(13Z)/22:2(13Z,16Z)) + S-Adenosylhomocysteine
