Thus, the two substrates of this enzyme are 11-cis-retinyl palmitate and H2O, whereas its two products are 11-cis-retinol and palmitate.
This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is 11-cis-retinyl-palmitate acylhydrolase. Other names in common use include 11-cis-retinol palmitate esterase, and RPH. This enzyme participates in retinol metabolism. This enzyme has at least one effector, Bile salt.
