Product Name phosphatidylcholine-retinol O-acyltransferase
Example Structure Example Structure of phosphatidylcholine-retinol O-acyltransferase EC#: 2.3.1.135
Synonyms 11-cis-acyl-CoA:retinol O-acyltransferase, acyltransferase, lecithin-retinol, lecithin retinol acyl transferase, lecithin retinol acyltransferase, lecithin-retinol acyltransferase, lecithin/retinol acyltransferase, lecithin: retinol acyltransferase, lecithin:retinol acyl transferase, lecithin:retinol acyltransferase, LRAT, More, retinyl ester synthase, retinyl-ester synthase
EC Number 2.3.1.135
CAS Registry Number 117444-03-8
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.
Cofactor
History
Reactions Phosphatidylcholine + retinol–[cellular-retinol-binding-protein] = 2-acylglycerophosphocholine + retinyl-ester–[cellular-retinol-binding- protein].
