Accepted name: diacylglycerol cholinephosphotransferase

Reaction: CDP-choline + 1,2-diacyl-sn-glycerol = CMP + a phosphatidylcholine

Other name(s): phosphorylcholine-glyceride transferase; alkylacylglycerol cholinephosphotransferase; 1-alkyl-2-acetylglycerol cholinephosphotransferase; cholinephosphotransferase; CPT (ambiguous); alkylacylglycerol choline phosphotransferase; diacylglycerol choline phosphotransferase; 1-alkyl-2-acetyl-m-glycerol:CDPcholine choline phosphotransferase; CDP-choline diglyceride phosphotransferase; cytidine diphosphocholine glyceride transferase; cytidine diphosphorylcholine diglyceride transferase; phosphocholine diacylglyceroltransferase; sn-1,2-diacylglycerol cholinephosphotransferase; 1-alkyl-2-acetyl-sn-glycerol cholinephosphotransferase; CDP choline:1,2-diacylglycerol cholinephosphotransferase; CDP-choline:1,2-diacylglycerol cholinephosphotransferase

Systematic name: CDP-choline:1,2-diacyl-sn-glycerol cholinephosphotransferase

Comments: 1-Alkyl-2-acylglycerol can act as acceptor; this activity was previously listed as EC, 1-alkyl-2-acylglycerol choline phosphotransferase.
