Urease is a nickel-dependent metalloenzyme , found in various plants, bacteria, fungi, and algae. It contains two distinct subunits-UreA(26.5 kDa) and UreB (60.3–61.6 kDa).
생화학적/생리학적 작용
Urease aids in the bioavailability of nitrogen in plants. It is implicated in defense mechanism and exhibits insecticidal activity. In addition, urease exhibits antifungal activity by retarding growth and affecting membrane integrity of filamentous fungi and yeasts.
Urease was shown to induce vacuolation in Hela cells, an effect dependent on the ability of urease to convert urea to ammonia.
단위 정의
One micromolar unit will liberate 1.0 μmole of NH3 from urea per min at pH 7.0 at 25 °C. It is equivalent to 1.0 I.U. or 0.054 Sumner unit (1.0 mg ammonia nitrogen in 5 minutes at pH 7.0 at 20 °C)

A pH-variation study of jack bean (Canavalia ensiformis) urease steady-state kinetic parameters and of the inhibition constant of boric acid, a urease competitive inhibitor, was performed using both noninhibitory organic (MES, HEPES and CHES) and inhibitory inorganic (phosphate) buffers, in

The resolution of cryo-EM reconstructions is fundamentally limited by the Nyquist frequency, which is half the sampling frequency of the detector and depends upon the magnification used. In principle, super-resolution imaging should enable reconstructions to surpass the physical Nyquist limit

Concentrated broth culture supernatants from 50 to 60% of Helicobacter pylori strains induce eukaryotic cell vacuolation in vitro. A quantitative assay for cell vacuolation was developed on the basis of the rapid uptake of visibly vacuolated HeLa cells was significantly

Recent studies showed that hyperammonaemia caused many of the metabolic changes in portacaval-shunted rats, a model of hepatic encephalopathy. These changes included a depression in the cerebral metabolic rate of glucose (CMRGlc), an indication of decreased brain function. 2. The

An epitope-based vaccine is a promising option for treating Helicobacter pylori (H. pylori) infection. Epitope mapping is the first step in designing an epitope-based vaccine. A pivotal role of CD4(+) T cells in protection against H. pylori has been accepted
