In enzymology, a phosphatidylcholine---dolichol O-acyltransferase () is an enzyme that catalyzes the chemical reaction 3-sn-phosphatidylcholine + dolichol 1-acyl-sn-glycero-3-phosphocholine + acyldolichol Thus, the two substrates of this enzyme are 3-sn-phosphatidylcholine and dolichol, whereas its two products are 1-acyl-sn-glycero-3-phosphocholine and acyldolichol. This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is 3-sn-phosphatidylcholine:dolichol O-acyltransferase. References EC 2.3.1 Enzymes of unknown structure
