In enzymology, a diacylglycerol cholinephosphotransferase (EC 2.7.8.2) 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.[1]

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.
