Metabolite Identification
Common NameImidazoleacetic acid
DescriptionImidazol-4-ylacetic acid is a monocarboxylic acid that is acetic acid in which one of the methyl hydrogens has been replaced by an imidazol-4-yl group. It has a role as a mouse metabolite. It is a monocarboxylic acid and a member of imidazoles. It derives from an acetic acid. It is a conjugate acid of an imidazol-4-ylacetate. It is a tautomer of an imidazol-5-ylacetic acid and a 2H-imidazol-4-ylacetic acid. Imidazoleacetic acid, also known as 4(5)-imidazoleacetate or IAA, belongs to the class of organic compounds known as imidazolyl carboxylic acids and derivatives. These are organic compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an imidazole ring. Imidazoleacetic acid exists in all living organisms, ranging from bacteria to humans. imidazoleacetic acid can be biosynthesized from imidazole-4-acetaldehyde through its interaction with the enzyme aldehyde dehydrogenase, mitochondrial. In humans, imidazoleacetic acid is involved in histidine metabolism. Outside of the human body, Imidazoleacetic acid has been detected, but not quantified in several different foods, such as chinese cinnamons, jostaberries, vanilla, butternut squash, and red rices. Imidazoleacetic acid is a potentially toxic compound. Imidazoleacetic acid is a metabolite product of Histamine metabolism.

Enzymes

Enzyme Details
1. 4-trimethylaminobutyraldehyde dehydrogenase
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
Enzyme Details
2. Alpha-aminoadipic semialdehyde dehydrogenase
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
Enzyme Details
3. Aldehyde dehydrogenase family 1 member A3
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).
