IUBMB Comments
This enzyme, abundant in the retinal pigment epithelium, catalyses the reduction of 11-cis-retinol to 11-cis-retinal while the substrate is bound to the retinal-binding protein . This is a crucial step in the regeneration of 11-cis-retinal, the chromophore of rhodopsin. The enzyme can also accept other cis forms of retinol .

11-cis-retinol:NAD+ oxidoreductase
This enzyme, abundant in the retinal pigment epithelium, catalyses the reduction of 11-cis-retinol to 11-cis-retinal [1] while the substrate is bound to the retinal-binding protein [4]. This is a crucial step in the regeneration of 11-cis-retinal, the chromophore of rhodopsin. The enzyme can also accept other cis forms of retinol [2].

the addition of NADP+ results in more efficient oxidation of all-trans retinol into all-trans retinal, when compared with the addition of NAD+, suggesting that RDH10 prefers NADP as the cofactor. At assay conditions (pH 5.5 and pH 7.6), and NADH or NADPH is used as the cofactor, only a low level of all-trans retinol is generated by RDH10

the multifunctional cis-retinol/3alpha-hydroxysterol short-chain dehydrogenase may catalyze the first step in an enzymatic pathway from 9-cis-retinol to generate the retinoid X receptor ligand 9-cis-retinoic acid and/or may regenerate dihydrotestosterone from its catabolite 5alpha-androstan-3alpha,17beta-diol
