Dynamic anti-correlations of water hydrogen bonds [PDF]

Nature Communications
Water is characterized by strong intermolecular hydrogen bonds (H-bonds) between molecules. The two hydrogen atoms in one water molecule can form H-bonds of dissimilar length. Although intimately connected to water’s anomalous properties, the details and

The role of backbone hydrogen bonds in the transition state for protein folding of a PDZ domain. [PDF]

PLoS ONE, 2014
Backbone hydrogen bonds are important for the structure and stability of proteins. However, since conventional site-directed mutagenesis cannot be applied to perturb the backbone, the contribution of these hydrogen bonds in protein folding and stability ...

Disposition of Federally Owned Surpluses [PDF]

, 1944
PDZ domains are scaffolding modules in protein-protein interactions that mediate numerous physiological functions by interacting canonically with the C-terminus or non-canonically with an internal motif of protein ligands. A conserved carboxylate-binding

A topologia molecular QTAIM e a descrição mecânico-quântica de ligações de hidrogênio e ligações de di-hidrogênio The QTAIM molecular topology and the quantum-mechanical description of hydrogen bonds and dihydrogen bonds

Química Nova, 2010
Hydrogen bonds formed through the interaction between a high electronic density center (lone electron pairs, π or pseudo-π bonds) and proton donors cause important electronic and vibrational phenomena in many systems.
