ID 3.1.1.64 DE retinoid isomerohydrolase. AN all-trans-retinylester 11-cis isomerohydrolase. AN all-trans-retinyl-palmitate hydrolase. CA an all-trans-retinyl ester + H2O = 11-cis-retinol + a fatty acid + H(+). CC -!- This enzyme, which operates in the retinal pigment epithelium (RPE), CC catalyzes the cleavage and isomerization of all-trans-retinyl fatty CC acid esters to 11-cis-retinol, a key step in the regeneration of the CC visual chromophore in the vertebrate visual cycle. CC -!- Interaction of the enzyme with the membrane is critical for its CC enzymatic activity. CC -!- Formerly EC 5.2.1.7.
