General description

Urease (urea amidohydrolase; EC 3.5.1.5) is a nickel-dependent metalloenzyme that is found in various plants, bacteria, fungi, algae, and even some invertebrates.

Biochem/physiol Actions

Urease catalyzes the hydrolysis of urea to ammonia and CO2. It is implicated in the development of enzymology and heme protein chemistry. Bacterial urease acts as a virulence factor and is involved in the pathogenesis of hepatic coma, peptic ulceration, and pyelonephritis.

Analysis Note

Activity: ≥ 5 U/mg
Suitability for determination of urea: passes test

    1. Dr. Timm Schlegelmilch from Life Science provided the following information: For 1.08489, 1U is defined as the amount of enzyme that catalyzes 1 µmol urea to ammonia and CO2 per minute, at 25°C and pH 8.0. Therefore, with the current specification of > 5 U/mg, it is guaranteed that each milligram of the product can catalyze the reaction of 5 µmol urea per minute.
