For the determination of urea (1).
Urease is involved in purine metabolism and the urea cycle. It hydrolyzes urea to produce ammonia and carbon dioxide.
Unit definition: 1 U catalyzes the formation of 1 µmole ammonia per minute at 25 °C, pH 8.0 from urea, determined in a coupled reaction with GLDH (2).
Activity in other units: If the unit of activity is defined in terms of 1 µmole urea decomposed per minute, this preparation would contain at least 90 units/mg.
