General description
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.
Subunit molecular weight: ~90,770
Composed of six subunits with total molecular weight: ~544,620
Application
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.
Biochem/physiol Actions
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 .
Other Notes
1 U corresponds to the amount of enzyme which hydrolyzes 1 μmol urea (Cat. No. 51459) per minute at pH 8.0 and 25 °C.
