In enzymology, a phosphatidylcholine---retinol O-acyltransferase (EC 2.3.1.135) is an enzyme that catalyzes the chemical reaction
- phosphatidylcholine + retinol--- 2-acylglycerophosphocholine + retinyl-ester---
Thus, the two substrates of this enzyme are phosphatidylcholine and ]], whereas its two products are 2-acylglycerophosphocholine and ]].
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 phosphatidylcholine:retinol--- O-acyltransferase. Other names in common use include lecithin---retinol acyltransferase, phosphatidylcholine:retinol-(cellular-retinol-binding-protein), and O-acyltransferase.
