Life needs interaction. The current pandemic has made visible how much interaction, or lack thereof, means for the life of each and every one of us. The validity of this statement also extends to the tiny and invisible: Over the years, scientists have taken key steps to understand the interactions... Read More

Internal cavities in proteins produce conformational fluctuations and enable the binding of small ligands. Here, we report a NMR analysis of O2-binding sites by O2-induced paramagnetic relaxation enhancements (PREs) on amide groups of proteins in solution. Outer...

Abstract
Electrostatics play an important role in many aspects of protein chemistry. However, the accurate determination of side chain proton affinity in proteins by experiment and theory remains challenging. In recent years the field of nuclear magnetic resonance spectroscopy has advanced the way that protonation states are measured, allowing...
