In enzymology, a diacylglycerol cholinephosphotransferase () is an enzyme that catalyzes the chemical reaction
<div align=center><small>CDP-choline + 1,2-diacylglycerol CMP + a phosphatidylcholine</small></div>
Thus, the two substrates of this enzyme are CDP-choline and 1,2-diacylglycerol, whereas its two products are CMP and phosphatidylcholine.
This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups.
The systematic name of this enzyme class is CDP choline:1,2-diacylglycerol cholinephosphotransferase. Other names in common use include:
This enzyme participates in 3 metabolic pathways: aminophosphonate metabolism, glycerophospholipid metabolism, and ether lipid metabolism.
