Metabolite Identification
Common Name6-Thiourate
Description6-Thiourate, also known as 6-thiouric acid, belongs to the class of organic compounds known as purinones. These are purines in which the purine moiety bears a C=O group. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. 6-Thiourate is an extremely weak basic (essentially neutral) compound (based on its pKa). 6-Thiourate exists in all living organisms, ranging from bacteria to humans. These are aromatic heterocyclic compounds containing a purine moiety, which is formed a pyrimidine-ring ring fused to an imidazole ring.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Key enzyme in purine degradation. Catalyzes the oxidation of hypoxanthine to xanthine. Catalyzes the oxidation of xanthine to uric acid. Contributes to the generation of reactive oxygen species. Has also low oxidase activity towards aldehydes (in vitro).
