EC 2.3.1.135     
Accepted name: phosphatidylcholine—retinol O-acyltransferase
Reaction: phosphatidylcholine + retinol—[cellular-retinol-binding-protein] = 2-acylglycerophosphocholine + retinyl-ester—[cellular-retinol-binding-protein]
Glossary: phosphatidylcholine = lecithin
Other name(s): lecithin—retinol acyltransferase; phosphatidylcholine:retinol-(cellular-retinol-binding-protein) O-acyltransferase; lecithin:retinol acyltransferase; lecithin-retinol acyltransferase; retinyl ester synthase; LRAT; lecithin retinol acyl transferase
Systematic name: phosphatidylcholine:retinol—[cellular-retinol-binding-protein] O-acyltransferase
Comments: A key enzyme in retinoid metabolism, catalysing the transfer of an acyl group from the sn-1 position of phosphatidylcholine to retinol, forming retinyl esters which are then stored. Recognizes the substrate both in free form and when bound to cellular-retinol-binding-protein, but has higher affinity for the bound form. Can also esterify 11-cis-retinol.
