ID 1.1.1.315 DE 11-cis-retinol dehydrogenase. CA 11-cis-retinol--[retinol-binding protein] + NAD(+) = 11-cis-retinal- CA -[retinol-binding protein] + H(+) + NADH. CC -!- This enzyme, abundant in the retinal pigment epithelium, catalyzes CC the reduction of 11-cis-retinol to 11-cis-retinal while the substrate CC is bound to the retinal-binding protein. CC -!- This is a crucial step in the regeneration of 11-cis-retinal, CC the chromophore of rhodopsin. CC -!- The enzyme can also accept other cis forms of retinol.
