應用
磷酸二酯酶（PDE）是一种可用于破坏磷酸二酯键的酶。 它是一种膜结合糖蛋白，可用于催化各种核苷酸多磷酸盐的水解。 磷酸二酯酶I可用于磷酸二酯酶活化检测实验中以水解AMP。 产品P3243来自于 响尾蛇（Crotalus adamanteus） 的毒液中，并已经过纯化。 产物P3243已被用于将含有怀俄苷衍生物的tRNA水解成单核苷。
生化／生理作用
磷酸二酯酶I可破坏磷酸二酯键并催化各种核苷酸多磷酸盐的水解。 通过磷脂酰肌醇特异性磷脂酶C从真核质膜中释放磷酸二酯酶I。

实验方案
在测定5′-核苷酸酶活性时，本操作流程使用5′-单磷酸腺苷和一种显色试剂生成的标准曲线而对释放的磷的微摩尔数进行测定。
To measure 5′-nucleotidase activity, this procedure uses adenosine 5’-monophosphate and a color reagent to create a standard curve for determining the micromoles of phosphorus liberated.
