ENZYME entry: EC

Accepted Name
Phosphatidylcholine--retinol O-acyltransferase.
Alternative Name(s)
Lecithin retinol acyl transferase.
Lecithin--retinol acyltransferase.
Lecithin-retinol acyltransferase.
Retinyl ester synthase.
Reaction catalysed
Phosphatidylcholine + retinol--[cellular-retinol-binding-protein] <=> 2-acylglycerophosphocholine + retinyl-ester--[cellular-retinol-binding-protein]
  • A key enzyme in retinoid metabolism, catalyzing 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.
