Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Converts gamma-trimethylaminobutyraldehyde into gamma-butyrobetaine. Catalyzes the irreversible oxidation of a broad range of aldehydes to the corresponding acids in an NAD-dependent reaction.
Gene Name:
ALDH9A1
Uniprot ID:
P49189
Molecular weight:
56291.485
Reactions
Imidazole-4-acetaldehyde + NAD + Water → Imidazoleacetic acid + NADH + Hydrogen Iondetails
General function:
Involved in oxidoreductase activity
Specific function:
Multifunctional enzyme mediating important protective effects. Metabolizes betaine aldehyde to betaine, an important cellular osmolyte and methyl donor. Protects cells from oxidative stress by metabolizing a number of lipid peroxidation-derived aldehydes. Involved in lysine catabolism.
Gene Name:
ALDH7A1
Uniprot ID:
P49419
Molecular weight:
58486.74
Reactions
Imidazole-4-acetaldehyde + NAD + Water → Imidazoleacetic acid + NADH + Hydrogen Iondetails
General function:
Involved in oxidoreductase activity
Specific function:
Recognizes as substrates free retinal and cellular retinol-binding protein-bound retinal. Seems to be the key enzyme in the formation of an RA gradient along the dorso-ventral axis during the early eye development and also in the development of the olfactory system (By similarity).

Gene Name:
ALDH2
Uniprot ID:
P05091
Molecular weight:
56380.93
Reactions
Imidazole-4-acetaldehyde + NAD + Water → Imidazoleacetic acid + NADH + Hydrogen Iondetails
General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the oxidation of long-chain aliphatic aldehydes to fatty acids. Active on a variety of saturated and unsaturated aliphatic aldehydes between 6 and 24 carbons in length. Responsible for conversion of the sphingosine 1-phosphate (S1P) degradation product hexadecenal to hexadecenoic acid.
Gene Name:
ALDH3A2
Uniprot ID:
P51648
Molecular weight:
54847.36
Reactions
Imidazole-4-acetaldehyde + NAD + Water → Imidazoleacetic acid + NADH + Hydrogen Iondetails
General function:
Involved in oxidoreductase activity
Specific function:
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.
Gene Name:
ALDH1B1
Uniprot ID:

General function:
Involved in copper ion binding
Specific function:
Catalyzes the degradation of compounds such as putrescine, histamine, spermine, and spermidine, substances involved in allergic and immune responses, cell proliferation, tissue differentiation, tumor formation, and possibly apoptosis. Placental DAO is thought to play a role in the regulation of the female reproductive function.
