EC Number Substrates Comment Substrates Organism Products Comment (Products) Rev. Reac. 11-cis-retinol-[cellular retinaldehyde binding protein] + NAD+ cellular retinaldehyde binding protein CRALBP serves as an 11-cis-retinol acceptor for the enzymatic isomerization of all-trans- to 11-cis-retinol and as a substrate carrier for 11-cis-retinol dehydrogenase RDH5. Altered kinetic parameters are observed for RDH5 oxidation of 11-cis-retinol bound to rCRALBP mutants M222A, M225A, and W244F, supporting impaired substrate carrier function. Data implicate Trp165, Met208, Met222, Met225, and Trp244 as components of the CRALBP ligand binding cavity Homo sapiens 11-cis-retinal-[cellular retinaldehyde binding protein] + NADH + H+
