RovM and CsrA Negatively Regulate Urease Expression in Yersinia pseudotuberculosis
Urease acts as an important acid resistance system and virulence factor that is widespread among microorganisms. RovM is a global regulator that regulates a series of genes and pathways including acid survival systems in the enteric bacterium Yersinia ...

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

Embryos extract from germinated yellow soybean (Glycine max [L.] Merrill) inhibits promastigotes form of Leishmania amazonensis [PDF]
We investigated the effect of extracts of the germinated seeds of yellow soybean cultivar BRS 258 (Glycine max [L.] Merrill) against Leishmania amazonensis promastigotes. The yellow soybean embryos extract (YSEE) was fractionated on a Sephacryl S-100 gel

Soil bacteria that precipitate calcium carbonate: mechanism and applications of the process
Bacteria with ureasic activity are microorganisms found in soil that in presence of urea and calcium, they can produce calcium carbonate, a process known as microbiologically induced calcium carbonate precipitation (MICP).

Inactivation of anti-nutrients in soybeans via micronisation
The soybean (Glycine max) is used as one of the main protein sources in various animal fodders. However, the presence of anti-nutrients significantly reduces the nutritional value of the bean.

Biosynthesis of the Urease Metallocenter [PDF]
Metalloenzymes often require elaborate metallocenter assembly systems to create functional active sites. The medically important dinuclear nickel enzyme urease provides an excellent model for studying metallocenter assembly. Nickel is inserted into the urease active site in a GTP-dependent process with the assistance of UreD/UreH, UreE, UreF, and UreG.
