General description

亚基分子量:约 90,770
由六个亚基组成,总分子量:约 544620

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.

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
