Choline/ethanolaminephosphotransferase 1
Ethanolamine-phosphate cytidylyltransferase
Glycerol 3-phosphate (→) Transport: Arabidopsis thaliana, Cell, Cytosol to Arabidopsis thaliana, Cell, Endoplasmic Reticulum
1-Acyl-sn-glycerol-3-phosphate acyltransferase 2
Phosphatidylserine decarboxylase proenzyme 3
Hydrogen Ion + L-Serine → Carbon dioxide + Ethanolamine
Adenosine triphosphate + Ethanolamine → Adenosine diphosphate + Hydrogen Ion + O-Phosphoethanolamine
an L-1-Phosphatidylethanolamine (→) Transport: Arabidopsis thaliana, Cell, Endoplasmic Reticulum to Arabidopsis thaliana, Cell, Cytosol
1,2-Diacyl-sn-glycerol 3-phosphate + Cytidine triphosphate → Pyrophosphate + a CDP-diacylglycerol
1,2-Diacyl-sn-glycerol + CDP-ethanolamine → Cytidine monophosphate + an L-1-Phosphatidylethanolamine
Glycerol 3-phosphate + Long-chain fatty acyl-CoA → 1-Acyl-sn-glycerol 3-phosphate + Coenzyme A
1-Acyl-sn-glycerol 3-phosphate + Long-chain fatty acyl-CoA → 1,2-Diacyl-sn-glycerol 3-phosphate + Coenzyme A
Dihydroxyacetone phosphate + Hydrogen Ion + NADH ↔ Glycerol 3-phosphate + NAD
CDP-diacylglycerol--serine O-phosphatidyltransferase
L-Serine + a CDP-diacylglycerol → Cytidine monophosphate + an L-1-Phosphatidylserine
Water + an L-1-Phosphatidylethanolamine → 1,2-Diacyl-sn-glycerol 3-phosphate + Ethanolamine
an L-1-Phosphatidylserine → Carbon dioxide + an L-1-Phosphatidylethanolamine
Water + an L-1-Phosphatidylethanolamine → 1,2-Diacyl-sn-glycerol + O-Phosphoethanolamine
Glycerol-3-phosphate dehydrogenase [NAD(+)]
Cytidine triphosphate + O-Phosphoethanolamine → CDP-ethanolamine + Pyrophosphate
