A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.3.1.135

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]
Comment(s)
  • 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.
