Dynamic anti-correlations of water hydrogen bonds [PDF]
Nature CommunicationsWater 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 ...
