EC 3.1.1.90

Accepted name: all-trans-retinyl ester 13-cis isomerohydrolase

Reaction: an all-trans-retinyl ester + H2O = 13-cis-retinol + a fatty acid

Systematic name: all-trans-retinyl ester acylhydrolase, 13-cis retinol forming

Comments: All-trans-retinyl esters, which are a storage form of vitamin A, are generated by the activity of EC 2.3.1.135, phosphatidylcholine—retinol O-acyltransferase (LRAT). They can be hydrolysed to 11-cis-retinol by EC 3.1.1.64, retinoid isomerohydrolase (RPE65), or to 13-cis-retinol by this enzyme.
