据报道,来自欧洲帽贝的酶比来自盖罩大蜗牛、牛肝脏和大肠杆菌的酶能更有效地水解阿片肽-葡糖苷酸

生化/生理作用

β-葡萄糖醛酸酶(β-GIc)是一种外切糖苷酶,催化复合碳水化合物的分解。在人体内可将结合胆红素转化为非结合形式,使胆红素适于重吸收。使用从 Patella vulgate 获得的 ß-葡糖苷酸酶将 3-β-D 葡糖苷酸转化为吗啡。

品質

含有被 0.1 M 磷酸盐抑制的硫酸酯酶活性。

單位定義

在37℃,pH 3.8(30分钟检测)条件下,一个Sigma或改良的Fishman单位可每小时从酚酞葡糖苷酸中释放1.0 μg酚酞。

Physicians determine patient compliance with their medications by use of urine drug testing. It is known that measurement of benzodiazepines is limited by immunoassay specificity and cutoff limits and therefore does not offer physicians an accurate picture of their patients'

Naltrexone is effective in treating opioid dependence by blocking µ, κ and δ opiate receptors. Naltrexone is mainly metabolized to an active metabolite 6β-naltrexol by dihydrodiol dehydrogenase enzymes. Concomitant opioids will not be effective while patients are taking this antagonist.

A method for the simultaneous qualitative and quantitative determination of drugs of abuse (opiates, cocaine, or amphetamines) and prescribed drugs (tricyclic antidepressants, phenotiazines, benzodiazepines, etc.) in biological fluids--blood, urine, bile, and gastric contents--was developed. This procedure involves solid-phase extraction with

beta-Glucuronidase from Patella vulgata, Helix aspersa, Helix pomatia, and bovine liver were evaluated for usefulness in routine hydrolysis of drug-glucuronic acid conjugates from equine urine samples. Factors affecting the reaction rate (enzyme concentration, ligand concentration, temperature, and pH) were optimized.

实验方案

Enzymatic Assay of ß-Glucuronidase (EC 3.2.1.31) from Helix Pomatia and Bovine Liver. This procedure applies to all b-Glucuronidase products that are derived from Helix Pomatia and Bovine Liver. It is the responsibility of trained Analytical Services laboratory personnel to follow this procedure as written.

It is the responsibility of trained Analytical Services laboratory personnel to follow this procedure as written.

To optimize hydrolysis using β-glucuronidase, factors such as incubation time, temperature, hydrolysis pH, enzyme source, and enzyme concentration must be evaluated for each glucuronide metabolite to be analyzed.
