COMMENTARY
LITERATURE
physiological function
-
effects of urease added to rabbit platelets are assessed turbidimetrically. Fluorescein-labelled HPU bound to platelets but not to erythrocytes. HPU induces aggregation of rabbit platelets accompanied by ATP secretion. No correlation is found between platelet activation and ureolytic activity of HPU
physiological function
-
growth studies demonstrate that Edwardsiella ictaluri is unable to grow at pH 5 in the absence of urea but is able to elevate the environmental pH from pH 5 to pH 7 and grow when exogenous urea is available
physiological function
-
the bacterium typically colonizes the mucosal lining of the stomach, where the increase in pH of the strongly acidic environment allows the bacterium that requires pH 6-8 to grow, to persist in the hostile conditions. Concomitantly it incurs damage to the host tissue, thereby giving rise to gastritis and gastroduodenal ulcers. The damaging factors are ammonia and monochloramine
physiological function
-
the biosynthesis of the active metal-bound form of the nickel-dependent enzyme urease involves the formation of a lysine-carbamate functional group concomitantly with the delivery of two Ni2+- ions into the precast active site of the apoenzyme and with GTP hydrolysis. In the urease system, this role is performed by UreG, an accessory protein belonging to the group of homologous P-loop GTPases
physiological function
-
urease is required for proliferation and virulence and for intracellular replication. Intracellular replication of wild-type Edwardsiella ictaluri is significantly enhanced when urea is present, indicating that urease plays an important role in intracellular survival and replication, possibly through neutralization of the acidic environment of the phagosome
physiological function
-
ureolytic bacterium responsible for the formation of urinary stones in human
metabolism
-
nitrogen metabolism, could be crucial for the pathogen's survival in nutrient-limited microenvironments where urea is the sole nitrogen source
additional information
-
ureases of Canavalia ensiformis are entomotoxic upon the release of internal peptides by insects digestive enzymes

using kinetic isotope effects it is shown that hydroxyurea exhibits biphasic kinetics with a rapid burst phase, followed by a very slow plateau phase. The plateau phase is attributed to irreversible substrate inhibition. The product, hydroxylamine, is shown to be a weak but reversible inhibitor of urease, it is not the cause of the plateau phase

This antifungal property of ureases is not affected by treatment of the proteins with an irreversible inhibitor of the ureolytic activity. Ureases probably contribute to the plant arsenal of defense compounds against predators and phytopathogens

5-hydroxy-1,4-naphthoquinone
-
5-hydroxy-1,4-naphthoquinone, juglone, acts as a strong, time and concentration dependent inactivator of urease. The reactivation of juglone-modified urease shows the participation of reversible and irreversible contribution in the inactivation. In the presence of an excess of DTT, urease inactivated by juglone regains 70% of its activity. The reversible inactivation is attributed to oxidation of the essential urease thiols by reactive oxygen species (ROS) realizing during reduction of juglone to seminaphthoquinone. The irreversible contribution in the inhibition is assumed as an arylation of urease thiol groups by juglone

additional information
additional information
-
sigmoid curve at low urea concentration (below 0.1 mM). In the presence of glycerol or PEG (preservatives), the sigmoid pattern changes to a rectangular hyperbola, and urea hydrolysis is consistent with Michaelis-Menten kinetics. Based on the kinetics of urease in the presence of the preservatives, the two forms of urease i.e., (alpha beta)3 and (alpha beta)6 may well exist in Helicobacter pylori. The hyperbolic kinetics adopted by the dissociated form of urease may allow for maximal urea assimilation by Helicobacter pylori under acidic conditions and at low urea concentration

optimal pH for urease activity in whole and permeabilized cells and of cell free extracts differs slightly, but is in the range 6.0-7.0. Significant activity is retained at pH 3.0 and 8.0, and, for cell free extracts, at pH 4.0 in the presence of ethanol. Urease production is evaluated in fermentations with pH control (5.25-6.5) and without pH control. Very little urease is produced in absence of urea, which at 5 g/l slows growth significantly in fermentations without pH control, but prevented a decrease in pH below 5.1 and results in higher final biomass. Optimal pH for growth is between 6.0 and 6.5 but specific urease activity is higher for fermentations at low pH at the beginning of the exponential phase. However, a higher total urease activity is obtained at pH 6.0 and 6.5 because of higher biomass

LITERATURE
urease is crystallized and the resulting crystals are diffracted to 2.05 A resolution using synchrotron radiation. The crystals belong to the hexagonal space group P6(3)322, with unit-cell parameters a = b = 138.57, c = 198.36 A
-
urease is crystallized at 2.05 A resolution. The active-site architecture of JBU is similar to that of bacterial ureases containing a bi-nickel center. JBU has a bound phosphate and covalently modified residue (Cys592) by beta-mercaptoethanol at its active site. By correlating the structural information of JBU with the available biophysical and biochemical data on insecticidal properties of plant ureases, it is hypothesized that the amphipathic beta-hairpin located in the entomotoxic peptide region of plant ureases might form a membrane insertion beta-barrel as found in beta-poreforming toxins

the immobilized enzyme is more stable in wet condition than in semi-dry condition and storing it at 4C is more favourable over 27C. There is a tremendous decrease in activity when the immobilized urease is not stored in buffer (i.e. semi-dry condition) and storing it at 4C improves the longevity. Both the alkyl and arylamine-urease in wet condition stored at 4C are further reused (30times) and the residual activity are 40% and 20%, respectively

COMMENTARY
LITERATURE
analysis
-
urea is estimated in different blood samples with the help of agar-immobilized urease and the results are consistent with those from clinical pathology laboratory through an autoanalyzer
biotechnology
-
immobilization of urease on arylamine glass beads results in improved thermal, storage and operational stability. Because of inertness of support and stability of immobilized urease, the preparation can find applications in artificial kidney and urea estimation in biological fluids
medicine
-
use of jack bean urease as a model enzyme for Helicobacter pylori urease. Development of organobismuth components without antifungal activity against Saccharomyces cerevisiae but with antibacterial activity

medicine
-
lack of enzyme activity in most enterohaemorrhagic strains is due to a premature stop codon in ureD encoding a chaperone protein of the urease gene cluster
biotechnology
-
soybean (Glycine max) urease is immobilized on alginate and chitosan beads and shows improved stability. This could have a potential role in haemodialysis machines
medicine
-
enhancement of intragastric enzyme activity is not strictly a function of pH-value, but is related to differential effects of the availability of nickel, which is required for enzyme activity
medicine
-
the action of urease in the upper intestinal tract is exploited in a non-invasive urease breath test for the diagnosis of bacterial infections of Helicobacter pylori: 13C- or 14C-labelled urea is ingested, and if the bacterium is present in the stomach, the urea is converted into isotope-labelled carbon dioxide. This is absorbed into the blood and exhaled in the breath, where it is detected by mass spectrometer or scintillation counter

in food industry immobilisation of acid urease on an inert carrier has the potential advantages of significant cost savings, improved stability or resistance to shear or inhibitory compound inactivation. Purified acid urease preparation is covalently immobilised onto biocompatible porous chitosan beads of different size. The kinetics of urea degradation in a model wine solution using this biocatalyst is of the pseudofirst order with respect to the urea concentration in the liquid bulk, the apparent pseudo-first order kinetic rate constant ranging from about two thirds to one fifth of that pertaining to free acid urease
