Journal ArticleDOI
A new proposal for urease mechanism based on the crystal structures of the native and inhibited enzyme from Bacillus pasteurii: why urea hydrolysis costs two nickels.
Stefano Benini,Wojciech Rypniewski,Keith S. Wilson,Silvia Miletti,Stefano Ciurli,Stefano Mangani +5 more
TL;DR: The mode of binding of the inhibitor, and a comparison between the native and inhibited urease structures, indicate a novel mechanism for enzymatic urea hydrolysis which reconciles the available structural and biochemical data.
Journal ArticleDOI
Structural properties of the nickel ions in urease: novel insights into the catalytic and inhibition mechanisms
Stefano Ciurli,Stefano Benini,Wojciech Rypniewski,Keith S. Wilson,Silvia Miletti,Stefano Mangani +5 more
TL;DR: In this article, a comprehensive critical summary of urease spectroscopy, crystallography, inhibitor binding, and site-directed mutagenesis, with special emphasis given to the relationships between the structural features of the Ni-containing active site and the physico-chemical and biochemical properties of this metallo-enzyme.
Journal ArticleDOI
The complex of Bacillus pasteurii urease with acetohydroxamate anion from X-ray data at 1.55 A resolution.
Stefano Benini,Wojciech Rypniewski,Keith S. Wilson,Silvia Miletti,Stefano Ciurli,Stefano Mangani +5 more
TL;DR: The structure of Bacillus pasteurii urease inhibited with acetohydroxamic acid was solved and refined anisotropically using synchrotron X-ray cryogenic diffraction data to show the binding mode of the inhibitor anion and the possible implications of the results on structure-based molecular design of new Urease inhibitors are discussed.
Journal ArticleDOI
Immobilization of jack bean urease on hydroxyapatite: urease immobilization in alkaline soils
TL;DR: Jack bean urease was adsorbed and immobilized on hydroxyapatite, a stable calcium phosphate mineral commonly found in alkaline soils and its stability and kinetic properties were investigated to derive a model that explains the stabilisation of Urease in alkali soil.
Journal ArticleDOI
Molecular characterization of Bacillus pasteurii UreE, a metal-binding chaperone for the assembly of the urease active site.
Stefano Ciurli,Niyaz Safarov,Silvia Miletti,Alexander Dikiy,Suzanne K. Christensen,Katja Kornetzky,Donald A. Bryant,Isabel Vandenberghe,Bart Devreese,Bart Samyn,Han Remaut,Jozef Van Beeumen +11 more
TL;DR: BpUreE has a high sequence similarity with UreE proteins isolated from different biological sources, while no sequence homology is observed with proteins belonging to different classes.
