Retinal isomerase

Retinal isomerase

In enzymology, a retinal isomerase (EC number|5.2.1.3) is an enzyme that catalyzes the chemical reaction

:all-trans-retinal ightleftharpoons 11-cis-retinal

Hence, this enzyme has one substrate, all-trans-retinal, and one product, 11-cis-retinal.

This enzyme belongs to the family of isomerases, specifically cis-trans isomerases. The systematic name of this enzyme class is all-trans-retinal 11-cis-trans-isomerase. Other names in common use include retinene isomerase, and retinoid isomerase. This enzyme participates in retinol metabolism.
