Metabolite Identification
Common Name5-Hydroxyindoleacetic acid
Description5-5-5-hydroxyindoleacetic acid, also known as 5-5-hydroxyindoleacetic acid or 5-hydroxy-1H-indole-3-acetate, belongs to the class of organic compounds known as indole-3-acetic acid derivatives. Indole-3-acetic acid derivatives are compounds containing an acetic acid (or a derivative) linked to the C3 carbon atom of an indole. 5-5-5-hydroxyindoleacetic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. 5-5-5-hydroxyindoleacetic acid exists in all living organisms, ranging from bacteria to humans. 5-5-5-hydroxyindoleacetic acid participates in a number of enzymatic reactions, within cattle. In particular, 5-5-5-hydroxyindoleacetic acid can be biosynthesized from 5-hydroxyindoleacetaldehyde through the action of the enzyme aldehyde dehydrogenase, mitochondrial. In addition, 5-5-5-hydroxyindoleacetic acid and S-adenosylmethionine can be converted into 5-methoxyindoleacetate and S-adenosylhomocysteine through its interaction with the enzyme acetylserotonin O-methyltransferase. In cattle, 5-5-hydroxyindoleacetic acid is involved in the metabolic pathway called the tryptophan metabolism pathway.

Enzymes

General function:
Secondary metabolites biosynthesis, transport and catabolism
Specific function:
Catalyzes the transfer of a methyl group onto N-acetylserotonin, producing melatonin (N-acetyl-5-methoxytryptamine).
Gene Name:
ASMT
Uniprot ID:
P10950
Molecular weight:
37924.0
Reactions
5-Hydroxyindoleacetic acid + S-Adenosylmethionine → 5-Methoxyindoleacetate + S-Adenosylhomocysteinedetails
General function:
Nucleotide transport and metabolism
Specific function:
Oxidase with broad substrate specificity, oxidizing aromatic azaheterocycles, such as N1-methylnicotinamide, N-methylphthalazinium and phthalazine, as well as aldehydes, such as benzaldehyde, retinal, pyridoxal, and vanillin. Plays a key role in the metabolism of xenobiotics and drugs containing aromatic azaheterocyclic substituents. Is probably involved in the regulation of reactive oxygen species homeostasis. May be a prominent source of superoxide generation via the one-electron reduction of molecular oxygen. Also may catalyze nitric oxide (NO) production via the reduction of nitrite to NO with NADH or aldehyde as electron donor. May play a role in adipogenesis.
