Urease (Ure) enzyme is present in the cytosol. It is active at acidic pH. Urease is present in archaea, bacteria, unicellular eukaryotes and plants.
应用
Urease from Canavalia ensiformis may be used for urea determination of various samples, such as legumes . It may be useful for the detection of pathogens as well as heavy-metal ions.
生化/生理作用
Urease catalyzes the hydrolysis of urea into carbon dioxide and ammonia. Urease is involved in nitrogen metabolism and urea degradation. Urease from Canavalia ensiformis binds 2 nickel ions per subunit .
单位定义
1 U corresponds to the amount of enzyme which hydrolyzes 1 μmol urea (Cat. No. 51459) per minute at pH 8.0 and 25℃
