Enzyme Information

1.1.1.54

Allyl-alcohol dehydrogenase.

based on mapping to UniProt O60218

Allyl alcohol + NADP(+) = acrolein + NADPH.

-!- Also acts on saturated primary alcohols.

1.1.1.300

NADP-retinol dehydrogenase.

based on mapping to UniProt O60218

All-trans-retinol + NADP(+) = all-trans-retinal + NADPH.

-!- 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. -!- Km-values for NADP(+) and NADPH are at least 800-fold lower than those for NAD(+) and NADH. -!- This enzyme differs from EC 1.1.1.105 which prefers NAD(+) and NADH. -!- Formerly EC 1.1.1.n2.
