l Biological Information |
Biochem/Physiol Actions | 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. |
Preparation Note | The enzyme is soluble in 0.2 M sodium phosphate buffer, pH 7.0, (10 mg/ml) yielding a solution with a possible haze. The following buffers have been shown not to inhibit urease activity: MES, HEPES, and CHES. |
Unit Definition | One micromolar unit will liberate 1.0 μmole of NH3 from urea per min at pH 7.0 at 25 °C. It is equivalent to 1.0 I.U. or 0.054 Sumner unit (1.0 mg ammonia nitrogen in 5 minutes at pH 7.0 at 20 °C) |
