144 Baehr, WolfgangRole of photoreceptor-specific retinol dehyrogenase (prRDH) in the retinoid cycle in vivoThe retinoid cycle is a recycling system that replenishes the 11-cis-retinal chromophore of rhodopsin and cone pigments. Photoreceptor-specific retinol dehydrogenase (prRDH) catalyzes reduction of all-trans-retinal to all-trans-retinol and is thought to be a key enzyme in the retinoid cycle.
