A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

Accepted Name
Retinoid isomerohydrolase.
Alternative Name(s)
All-trans-retinyl-palmitate hydrolase.
All-trans-retinylester 11-cis isomerohydrolase.
Reaction catalysed
An all-trans-retinyl ester + H(2)O <=> 11-cis-retinol + a fatty acid
  • This enzyme, which operates in the retinal pigment epithelium (RPE), catalyzes the cleavage and isomerization of all-trans-retinyl fatty acid esters to 11-cis-retinol, a key step in the regeneration of the visual chromophore in the vertebrate visual cycle.
  • Interaction of the enzyme with the membrane is critical for its enzymatic activity.
  • Formerly EC
