ALDH1B1

Functionⁱ

ALDHs play a major role in the detoxification of alcohol-derived acetaldehyde. They are involved in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and lipid peroxidation. In the cornea, this enzyme may help in the absorption of the damaging UV-B, as well as in the detoxification of the UV-induced peroxidic aldehydes.

Catalytic activityⁱ

An aldehyde + NAD⁺ + H₂O = a carboxylate + NADH.

Pathwayⁱ: ethanol degradation

This protein is involved in step 2 of the subpathway that synthesizes acetate from ethanol.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:

no protein annotated in this organism
Aldehyde dehydrogenase X, mitochondrial (ALDH1B1), Aldehyde dehydrogenase, mitochondrial (ALDH2), Aldehyde dehydrogenase family 3 member B1 (ALDH3B1)

This subpathway is part of the pathway ethanol degradation, which is itself part of Alcohol metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes acetate from ethanol, the pathway ethanol degradation and in Alcohol metabolism.
