Background ALDH3A1, also known as Aldehyde dehydrogenase 3 family memberA1, is involved in the detoxification of alcohol-derived acetaldehyde and in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and lipid peroxidation. This protein forms a cytoplasmic homodimer that preferentially oxidizes aromatic and medium-chain (6 carbons or more) saturated and unsaturated aldehyde substrates. It is thought to promote resistance to UV and 4-hydroxy-2-nonenal-induced oxidative damage in the cornea.

Biological activity:
Specific activity is < 1 unit/ml and was obtained by measuring the increase of NADP in absorbance at 340 nm resulting from the reduction of NAD.
One unit will oxidize 1.0 umole of acetaldehyde to acetic acid per minute at pH 8.0 at 25°C in the presence of beta-NAD, potassium and thiols.


Activity Assay
1. Prepare a 3 ml reaction mixture into a suitable container: The final concentrations are 103 mM Tris, 0.67 mM beta-NAD, 100 mM potassium chloride, 10 mM 2-mercaptoethanol, 2 mM acetaldehyde, 0.0007 % (w/v) BSA.
2. Equilibrate to 25°C and monitor the A340nm until the value is constant using a spectrophotometer.
3. Add 2.5 ug of recombinant ALDH3A1 into reaction mixture and mix immediately.
4. Record the increase in A340nm for 5 minutes.
