SpletThe Maturation Pathway of Nickel Urease. 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. Here, we review our current understandings on how these urease accessory proteins facilitate the... SpletThe active site of urease contains two nickel atoms bound to histidines and an aspartate and bridged by a carboxylated lysine and a solvent molecule. The enzyme catalyzes the cleavage of urea into ammonia and carbamate, which spontaneously hydrolyzes into bicarbonate and a second molecule of ammonia.
SpletUrease has a nickel-containing active site and catalyzes the hydrolysis of urea to yield ammonia and carbamate. In the present study, the role of nickel ions is examined using molecular dynamics simulations of the holo and apo forms. Nonbonded models used for the nickel ions provide good reproduction of the active-site structure as indicated in ... SpletThe infant gut commensal Bifidobacterium longum subsp. infantis utilizes urea as a primary nitrogen source. B. infantis strains were evaluated for urea utilization as a primary nitrogen source. As B. infantis is auxotrophic for L-cysteine, this amino acid was added in limiting concentrations to restrict its use as a general nitrogen source. Significantly, all B. infantis …
Splet19. dec. 2024 · The nickel-charged UreE dimer, providing the sole source of nickel, and the UreG 2 F 2 H 2 complex could activate urease in vitro in the presence of GTP. Based on our results, we propose a mechanism of how conformational changes of UreG during the GTP hydrolysis/binding cycle facilitate urease maturation.
