^(19)F NMR spectroscopy has recently witnessed a resurgence as an attractive analytical tool for the study of the structure and dynamics of biomolecules in vitro and in cells, despite reports of its applications in biomolecular NMR since the 1970s. The high gyromagnetic ratio, large chemical shift dispersion, and complete absence of the spin 1/2 ^(19)F nucleus from biomolecules results in background-free, high-resolution ^(19)F NMR spectra. The introduction of ^(19)F probes in a few selected...

Characterization of backbone dynamics using solution NMR spectroscopy to discern the functional plasticity of structurally analogous proteins
The comprehensive delineation of inherent dynamic motions embedded in proteins, which can be crucial for their functional repertoire, is often essential yet remains poorly understood in the majority of cases. In this protocol, we outline detailed descriptions of the necessary steps for employing solution NMR spectroscopy for the in-depth amino acid level understanding of backbone dynamics of proteins. We describe the application of the protocol on...

[NMR paper] Mechanistic Insights into Nanoparticle Surface Adsorption by Solution NMR Spectroscopy in an Aqueous Gel
Mechanistic Insights into Nanoparticle Surface Adsorption by Solution NMR Spectroscopy in an Aqueous Gel
Engineering nanoparticle (NP) functions at molecular level requires a detailed understanding of the dynamic processes occurring at the NP surface. Here we show that the combined analysis of Dark state Exchange Saturation Transfer (DEST) and Relaxation Dispersion (RD) NMR experiments acquired on gel-stabilized samples of NP allows for accurate determination of the kinetics and thermodynamics of adsorption. We used the former approach to describe the interaction of cholic acid (CA) and...

Many membrane peptides and protein domains contain functionally important cationic Arg and Lys residues, whose insertion into the hydrophobic interior of the lipid bilayer encounters significant energy barriers. To understand how these cationic molecules overcome the free energy barrier to insert into the...
