retinol:NADP+ oxidoreductase
Greater catalytic efficiency in the reductive direction. This observation, and the enzyme's localization at the entrance to the mitochondrial matrix, suggest that it may function to protect mitochondria against oxidative stress associated with the highly reactive retinal produced from dietary beta-carotene by EC 1.13.11.63 (beta-carotene 15,15'-dioxygenase) [2]. Km-values for NADP+ and NADPH are at least 800-fold lower than those for NAD+ and NADH [1,4]. This enzyme differs from EC 1.1.1.105, retinol dehydrogenase, which prefers NAD+ and NADH.
