一般描述
来自勃艮第蜗牛的β-葡萄糖醛酸苷酶H-2型是一种源自罗马蜗牛的酶的粗溶液。许多衍生自软体动物的β-葡萄糖醛酸苷酶也具有硫酸酯酶活性。
应用
β-葡萄糖醛酸苷酶可用于通过尿液技术进行的芳香化测定，适用于对芳香化酶抑制剂进行体内评估 。
来自勃艮第蜗牛的β-葡萄糖醛酸苷酶已被用于：
- 在尿液和豆浆样品中，将异黄酮结合物转化为苷元形式，从而用于高效液相色谱(HPLC)检测
- 用作原生质体溶液中的成分
- 用于从血浆和尿液样品中生成芳香族和酚类化合物，从而用于气相色谱-质谱(GC-MS)
- 水解粪便样品中的葡萄糖醛酸苷和硫酸盐共轭代谢物
质量
来自软体动物的多种β-葡糖醛酸糖苷酶也含有硫酸酯酶活性。
单位定义
在pH 5.0、温度37°C条件下，一单元sigma或改良的Fishman单元1小时会从酚酞葡糖苷酸释放 1.0 μg酚酞（30分钟实验）。
硫酸酯酶单元定义：一单位的硫酸酯酶每小时，pH5.0，37℃能够水解1.0 μmole p-硝基儿茶酚硫酸盐。
外形
在~1.0 M硫酸铵中含有3 mM叠氮化钠作为保存剂的水相溶液。
