Extraction and Characterization of Urease from Durio zibethinus L

open access: yesJurnal Kimia Valensi, 2021
Urease is a biocatalyst that serves to hydrolyze urea into ammonia and carbon dioxide. Since it is an imported product, the price of urea is still high. Urease can be found in grains. One of the grains that has not been explored for its urease content is

The Generation of Successive Unmarked Mutations and Chromosomal Insertion of Heterologous Genes in Actinobacillus pleuropneumoniae Using Natural Transformation [PDF]

open access: yes, 2014
We have developed a simple method of generating scarless, unmarked mutations in Actinobacillus pleuropneumoniae by exploiting the ability of this bacterium to undergo natural transformation, and with no need to introduce plasmids encoding recombinases or

RovM and CsrA Negatively Regulate Urease Expression in Yersinia pseudotuberculosis

open access: yesFrontiers in Microbiology, 2018
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 ...

The Glutaminase-dependent system confers extreme acid resistance to new species and atypical strains of Brucella [PDF]

open access: yes, 2017
Neutralophilic bacteria have developed specific mechanisms to cope with the acid stress encountered in environments such as soil, fermented foods, and host compartments. In Escherichia coli, the glutamate decarboxylase (Gad)-dependent system is extremely

The Maturation Pathway of Nickel Urease

open access: yesInorganics, 2019
Maturation of urease involves post-translational insertion of nickel ions to form an active site with a carbamylated lysine ligand and is assisted by urease accessory proteins UreD, UreE, UreF and UreG.

Development of a M9‐based urea medium (M9U) for sensitive and real‐time monitoring of ureolytic activity of bacteria and cell‐free urease

open access: yesMicrobiologyOpen, 2020
The enzyme urease is widespread in nature and catalyzes the hydrolysis of urea to form ammonia and carbonic acid. The high proficiency of the enzyme is associated with a wide range of societal challenges.
