In enzymology, a diacylglycerol cholinephosphotransferase () is an enzyme that catalyzes the chemical reaction
CDP-choline + 1,2-diacylglycerol CMP + a phosphatidylcholine
Thus, the two substrates of this enzyme are CDP-choline and 1,2-diacylglycerol, whereas its two products are CMP and phosphatidylcholine.
Classification
This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups.
Nomenclature
The systematic name of this enzyme class is CDP choline:1,2-diacylglycerol cholinephosphotransferase. Other names in common use include:
1-alkyl-2-acetyl-m-glycerol:CDPcholine choline phosphotransferase, 1-alkyl-2-acetyl-sn-glycerol cholinephosphotransferase, 1-alkyl-2-acetylglycerol cholinephosphotransferase, alkylacylglycerol choline phosphotransferase, alkylacylglycerol cholinephosphotransferase, CDP-choline diglyceride phosphotransferase, cholinephosphotransferase, CPT, cytidine diphosphocholine glyceride transferase, cytidine diphosphorylcholine diglyceride transferase, diacylglycerol choline phosphotransferase, phosphocholine diacylglyceroltransferase, phosphorylcholine-glyceride transferase, and sn-1,2-diacylglycerol cholinephosphotransferase.
Biological role
This enzyme participates in 3 metabolic pathways: aminophosphonate metabolism, glycerophospholipid metabolism, and ether lipid metabolism.
