Retinol dehydrogenase with a clear preference for NADP. Displays high activity towards 9-cis, 11-cis and all-trans-retinol. Shows a very weak activity towards 13-cis-retinol. Has no activity towards steroids. all-trans-retinol + NADP(+) = all-trans-retinal + H(+) + NADPH 11-cis-retinol + NADP(+) = 11-cis-retinal + H(+) + NADPH 9-cis-retinol + NADP(+) = 9-cis-retinal + H(+) + NADPH Shows clear specificity for the pro-S hydrogen on C4 of NADPH and the pro-R hydrogen on C15 of retinols. Belongs to the short-chain dehydrogenases/reductases (SDR) family.
