| 11-cis-retinol + NAD+ | Homo sapiens | Rdh5 catalyses 9-cis-retinol metabolism equally efficiently as 11-cis-retinol metabolism. Substrate specificity and expression locus of Rdh5 suggest that it could serve as both an 11-cis-retinol dehydrogenase in the RPE and a 9-cis-retinol dehydrogenase and/or an androgen dehydrogenase outside of the retinal pigment epithelium | 11-cis-retinal + NADH | - |
