Metabolite Identification
Common NameTyramine
DescriptionTyramine, also known as para-tyramine or systogene, belongs to the class of organic compounds known as phenethylamines. Phenethylamines are compounds containing a phenethylamine moiety, which consists of a phenyl group substituted at the second position by an ethan-1-amine. Tyramine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. Tyramine exists in all living species, ranging from bacteria to humans. Tyramine participates in a number of enzymatic reactions, within cattle. In particular, Tyramine can be biosynthesized from L-tyrosine; which is catalyzed by the enzyme aromatic-L-amino-acid decarboxylase. In addition, Tyramine can be converted into dopamine; which is mediated by the enzyme tyrosinase. In cattle, tyramine is involved in the metabolic pathway called the tyrosine metabolism pathway. Tyramine is a potentially toxic compound. Tyramine has been found to be associated with several diseases known as brunner syndrome, ulcerative colitis, crohn's disease, and eosinophilic esophagitis; also tyramine has been linked to the inborn metabolic disorders including celiac disease.

General function:
Involved in copper ion binding
Specific function:
This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the initial and rate limiting step in the cascade of reactions leading to melanin production from tyrosine. In addition to hydroxylating tyrosine to DOPA (3,4-dihydroxyphenylalanine), also catalyzes the oxidation of DOPA to DOPA-quinone, and possibly the oxidation of DHI (5,6-dihydroxyindole) to indole-5,6 quinone.
