Site-Selective Dynamics of Ligand-Free and Ligand-Bound Azidolysozyme [PDF]
, 2021 Azido-modified alanine residues (AlaN$_3$) are environment-sensitive, minimally invasive infrared probes for the site-specific investigation of protein structure and dynamics. Here, the capability of the label is investigated to query whether or not a ligand is bound to the active site of Lysozyme and how the spectroscopy and dynamics change upon ...

The Reaction Mechanism of the Azide-Alkyne Huisgen Cycloaddition [PDF]
Phys. Chem. Chem. Phys., 2019, 21, 19281-19287, 2020 The azide-alkyne Huisgen cycloaddition has a key role in click chemistry and configures as powerful tool in pharmaceutical and medicinal chemistry. Although this reaction has already been largely studied, there is an ongoing debate about its mechanism. In this work we study the dynamical aspects of the process using metadynamics computer simulation. We
