Urease is a nickel-dependent metalloenzyme , found in various plants, bacteria, fungi, and algae. It contains two distinct subunits-UreA(26.5 kDa) and UreB (60.3–61.6 kDa).

 

在 Hela 细胞中，脲酶可诱导空泡化，这种作用取决于脲酶将尿素转化为氨的能力。 [1]

Urease aids in the bioavailability of nitrogen in plants. It is implicated in defense mechanism and exhibits insecticidal activity. In addition, urease exhibits antifungal activity by retarding growth and affecting membrane integrity of filamentous fungi and yeasts.

 

一微摩尔单位，在 pH7.0，25℃ 下，每分钟从尿素中释放出 1.0 μmole 的 NH₃。它相当于1.0 I.U. 或 0.054 Sumner 单位（在 pH 7.0，20°C，5 分钟内 1.0 mg 氨氮）
