Uricase 9002-12-4: Decoding the "Biocatalyst" of Uric Acid Metabolism

Uricase is a key biological enzyme in the human metabolism and medical detection system, serving as both a "metabolic regulator" and a "detection assistant". It can accurately catalyze uric acid oxidation and provide biological solutions for high uric acid related problems.

1, The essence of uricase: from name to core catalytic mechanism

Uricase, also known as uric acid oxidase, exists in microorganisms (bacteria, fungi) and some animal bodies. Its core function is to specifically catalyze the oxidation of uric acid - with the participation of oxygen, uric acid is rapidly converted into uric acid precursor, which in turn generates soluble metabolites. At room temperature, the solubility of uric acid is only about 6 milligrams per liter, while the solubility of allantoin is more than 10 times higher, solving the problem of excretion.

Uricase

At the molecular level, uricase relies on the active center copper or iron ions to precisely bind to the uric acid purine ring, breaking chemical bonds and promoting oxygen insertion to trigger oxidative cleavage. This specificity ensures that it does not interfere with other purine metabolism, laying the foundation for the "precision" of medical applications.

2, The 'ruler' of clinical testing: the application of uricase in uric acid quantification

In clinical diagnosis, uricase is the "gold standard" for serum and urine uric acid quantification. The principle is that enzymatic reactions can be quantified: uricase reacts with the sample uric acid to generate hydrogen peroxide, which reacts with the color reagent under the action of peroxidase to generate colored substances. By detecting the absorbance and combining it with the standard curve, the uric acid concentration can be accurately calculated.

This method has high sensitivity, strong specificity, and rapid response, and is widely used for the diagnosis and monitoring of hyperuricemia, gout, and renal dysfunction. If serum uric acid is measured by uricase method during physical examination, the risk of high uric acid can be detected early; Regularly measuring urine uric acid during gout treatment can provide a basis for medication adjustment and avoid urate deposition.

3, The 'assistant' of metabolic regulation: the value of uricase in the treatment of hyperuricemia

For patients with hyperuricemia, the core value of uricase is to reduce the uric acid load in the body and improve retention. When there is excessive production or excretion of uric acid in the human body, blood uric acid levels rise, which can easily form urate crystals that deposit in joints, kidneys, etc., causing gout, kidney stones, and even kidney failure. Exogenous supplementation of uricase (such as recombinant preparations) can accelerate the oxidation and decomposition of blood uric acid into allantoin, rapidly reducing uric acid levels.

Meanwhile, uricase can promote the dissolution and excretion of deposited urate salts in tissues. Research has shown that uricase preparations can improve metabolic disorders, reduce gout attacks, and protect kidney function in refractory patients who are ineffective with traditional drugs such as allopurinol and febuxostat. However, currently its formulations are mostly administered by injection and have immunogenicity risks, and process optimization is still ongoing.

4, Research progress and future prospects

Currently, the application scenarios of uricase are constantly expanding, and researchers are exploring its role in the food industry (reducing beer uric acid) and environmental treatment (degrading uric acid wastewater). In the field of medicine, genetic engineering promotes the research and development of recombinant uricase. Modifying the molecular structure can prolong the half-life in the body, reduce immunogenicity, and create possibilities for long-term treatment.

In the future, with the development of precision medicine, uricase therapy is expected to combine genetic testing and personalized medication to achieve precise intervention for high uric acid diseases. In depth research on its mechanism of action will also provide ideas for the development of new uric acid lowering drugs and help improve the health of high uric acid patients.
