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 symmetryI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
