In enzymology a retinal isomerase (EC 5.2.1.3) is an enzyme that catalyzes the chemical reactionall-trans-retinal 11-cis-retinalHence 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.
