Urease (Ure) enzyme is present in the cytosol. It is active at acidic pH and is expressed at 28°C. Urease consists of nickel and is present in archaea, bacteria, unicellular eukaryotes and plants.
애플리케이션
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.
Urease from Canavalia ensiformis (Jack bean) has been used in purification and crystallization studies.
생화학적/생리학적 작용
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 .
