Urease-Immobilized PEI Cryogels for the Enzymatic Hydrolysis of Urea and Carbon Dioxide Uptake

, 2022
Here, the immobilization of the urease enzyme within polyethyleneimine (PEI) cryogels (Urease@PEI cryogel) is reported during the synthesis via the entrapment method. The immobilization yield of the enzymes within PEI cryogels was determined as >85%, and

Explaining Urease Specificity Towards Nickel: A Re-Analysis of Its Proposed Mechanism [PDF]

, 2020
Urease is a binuclear metalloenzyme selective towards nickel, exhibiting a remarkable rate enhancement of the catalytic reaction. The accepted mechanism for urease describes the coordination of urea to both nickel centers in an O,N bridged mode ...

THE ACTIVATION OF UREASE [PDF]

Journal of General Physiology, 1949
1. It has been shown that the activity of solutions of twice recrystallized urease is reversibly increased by moderate heating and reversibly decreased by storage in the cold, even in the frozen state. 2. Crude extracts of jack bean meal containing potent urease undergo this same type of reversible activation by heating and inactivation ...
