Lack of photoisomerization of retinoids to 11-cis-retinal in eyecups derived from rgr−/− and WT mice. Separation chromatograms of retinoids from eyecups incubated in the dark (a and a′); after an intense bleach (b and b′); or after constant white light illumination at 100 fc (c and c′). 1, 13-cis-retinyl esters; 2, 11-cis-retinyl esters; 3, all-trans-retinyl esters; 4, syn-11-cis-retinal oximes; 5, syn-all-trans-retinal oximes. Omission of CRALBP or NAD/NADH did not affect production of 11-cis-retinals.
