The enzyme retinoid isomerohydrolase (EC 3.1.1.64, all-trans-retinyl-palmitate hydrolase) catalyzes the reaction

an all-trans-retinyl ester + H2O = 11-cis-retinol + a fatty acid

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name is all-trans-retinyl ester acylhydrolase, 11-cis retinol-forming. This enzyme participates in retinol metabolism.
