Specifications

Aldehyde Dehydrogenases (ALDHs) are NAD(P)+- dependent enzymes that catalyze the oxidation of endogeneously produced and exogeneous aldehydes to their corresponding acids (1). They are involved in the detoxification of alcohol-derived acetaldehyde and in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and in lipid peroxidation. ALDH3A1 is also known as stomach aldehyde dehydrogenase. It exists as a homodimer, and prefers NADP+ over NAD+ as its co-factor (2). It preferentially oxidizes aromatic and medium-chain (6 carbons or more) saturated and unsaturated aldehyde substrates (3). The enzyme is highly expressed in stomach and cornea (2, 4). In the cornea, its proposed roles have been to absorb UV-light, reduce oxidative damage, maintain corneal refractive and transparence properties, and display chaperone-like activity (4, 5). It also has been identified as a lung cancer biomarker (6).
