Molecular analysis of 3D domain swapping in the acylphosphatase from Escherichia coli

Acta Crystallographica Section D, Volume 82, Issue 4, Page 336-347, April 2026.
Structures of the monomer and intertwined dimer of the acylphosphatase from E. coli shed light on the molecular basis of its 3D domain swapping.Three‐dimensional domain swapping is a mechanism by which proteins form oligomers. At present, the molecular basis that dictates whether some proteins fold in their monomeric form or as intertwined oligomers is

Molecular structure and nickel‐binding capacity of Proteus mirabilis UreE

Acta Crystallographica Section D, Volume 82, Issue 4, Page 348-357, April 2026.
This study presents a 2.0 Å resolution crystal structure and determined the nickel‐binding capacity of the P. mirabilis nickel chaperone UreE. UreE is essential for the delivery of nickel to the metalloenzyme urease, which is key for the ability of P. mirabilis to cause urinary‐tract infections.UreE is a nickel chaperone that is required for the safe ...

Eddington-inspired Born-Infeld gravity: nuclear physics constraints and the validity of the continuous fluid approximation

, 2012
In this paper we investigate the classical non-relativistic limit of the Eddington-inspired Born-Infeld theory of gravity. We show that strong bounds on the value of the only additional parameter of the theory \kappa, with respect to general relativity ...
