BRITE hierarchy
Sysname
11-cis-retinol:NAD+ oxidoreductase
Reaction(IUBMB)
11-cis-retinol---[retinal-binding-protein] + NAD+ = 11-cis-retinal---[retinol-binding-protein] + NADH + H+
Reaction(KEGG)
Substrate
11-cis-retinol---[retinal-binding-protein];
NAD+ [CPD:
C00003 ]
Product
11-cis-retinal---[retinol-binding-protein];
NADH [CPD:
C00004 ];
H+ [CPD:
C00080 ]
Comment
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].
