[PDF] Enzymatic Assay of UREASE (EC 3515) PRINCIPLE

Enzyme kinetics: Splitting urea with urease

The enzyme urease is to be investigated in this experiment This enzyme occurs frequently in nature in plants Here it catalyses the reaction in an aqueous medium of urea to am-monia and carbon dioxide, or to ammonium and carbonate ions (see Fig 2) Fig 2: Decomposition of urea to ammonium and carbonate ions

used for the enzyme reactions were reaction mixture without substrate and reaction mixture without incubation One unit of urease activity was defined as the amount of enzyme liberating 1 mg NH 3 from urea per minute, under the above assay conditions [11] The bacterium showing maximum enzyme activity on urease

Urease, Type III U1500 Product Description

Urease Urea + H 2O → CO 2 + 2 NH 3 Hydroxyurea is also a substrate of the enzyme 1 Jack bean urease was the first enzyme to be crystallized and the first enzyme found to contain nickel It is a multi-subunit enzyme, consisting of 91kDa subunits in three protein forms The major protein form has a molecular mass range of 440–480 kDa and two
