PubMed Abstract:
Zinc ions bridging two ubiquitin molecules (with His68 at the interface) contribute to select a subset of conformers from the noncovalent dimer ensemble, thus restricting quaternary structure dynamics, which hampers apo-protein crystallization. The type of selected conformer is shown to determine the crystal packing, which varies from orthorhombic to cubic symmetry.
