Sysname
phosphatidylcholine:retinol---[cellular-retinol-binding-protein] O-acyltransferase
Reaction(IUBMB)
phosphatidylcholine + retinol---[cellular-retinol-binding-protein] = 2-acylglycerophosphocholine + retinyl-ester---[cellular-retinol-binding-protein] [RN:
R04514 ]
Reaction(KEGG)
Substrate
phosphatidylcholine [CPD:
C00157 ];
retinol---[cellular-retinol-binding-protein]
Product
2-acylglycerophosphocholine;
retinyl-ester---[cellular-retinol-binding-protein]
Comment
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.
