尿素酶（脲酶）是一种多亚基的镍依赖型金属酶。大量存在于真菌、酵母、植物和细菌中。属于酰胺水解酶和磷酸三酯酶超家族。尿素酶也存在于豆科植物种子中。
应用
洋刀豆尿素酶已用于：
- 作为电泳的分子量标准品组分
- 作为体积排阻色谱的标准品组分
- 作为天然聚丙烯酰胺凝胶电泳(PAGE)的参比物质
生化/生理作用
尿素酶是氮循环的必需酶。它催化尿素分解成为氨和甲酸。尿素酶为各种生物提供生长所需氮源。在种子发芽和种子化学防御中同样发挥重要作用。

Urea is the most popular and widely used nitrogenous fertilizer. High soil urease activity rapidly hydrolyses applied urea to ammonia which contributes to soil nitrogen (N) losses and reduces N use efficiency of crop plants. The ammonia losses can be

mTORC1 promotes cell growth in response to nutrients and growth factors. Insulin activates mTORC1 through the PI3K-Akt pathway, which inhibits the TSC1-TSC2-TBC1D7 complex (the TSC complex) to turn on Rheb, an essential activator of mTORC1. However, the mechanistic basis of how
