生物活性/药理作用 | Urease from Canavalia ensiformis functions as an insecticide by the release of a toxic small peptide cleaved by proteases found in the gut of insects. |
样品准备说明 | The enzyme is soluble in 0.2M sodium phosphate buffer, pH7.0, (10mg/ml) yielding a solution with a possible haze. The following buffers have been shown not to inhibit urease activity: MES, HEPES, and CHES. |
有效单位定义 | One micromolar unit will liberate 1.0μmole of NH3 from urea per min at pH7.0 at 25°C. It is equivalent to 1.0 I.U. or 0.054 Sumner unit (1.0mg ammonia nitrogen in 5 minutes at pH7.0 at 20°C) |
