Protein

Aldehyde dehydrogenase, cytosolic 1

Gene

ALDH1

Organism
Elephantulus edwardii (Cape long-eared elephant shrew)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Major component of the eye of elephant shrews, which in contrast to other mammals, possesses both a lens- and a non-lens class-1 aldehyde dehydrogenase 1. This eye-specific form is a structural protein of the lens and, in other part of the eye, serves as the major form of ALDH1. Can convert/oxidize retinaldehyde to retinoic acid.1 Publication

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:
  1. no protein annotated in this organism
  2. Aldehyde dehydrogenase, cytosolic 1 (ALDH1)
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.
