The utilization of fluorine probes in protein research has advanced our understanding of the nature of macromolecules. The diverse activities of proteins are governed by intricate weak interaction networks, yet the experimental detection presents a challenge. Herein, we have developed an NMR analytical method based on quantum coherent operations to characterize the weak chemical bonds of fluorine atoms within proteins that are bound to metal fluorides or labeled with fluorinated amino acids. Our...

[NMR paper] Use of Fluorine Pseudocontact Shifts to Characterize the Protein-Ligand Interaction Mode in the Limit of NMR Intermediate Exchange
Use of Fluorine Pseudocontact Shifts to Characterize the Protein-Ligand Interaction Mode in the Limit of NMR Intermediate Exchange
The characterization of protein-ligand interaction modes becomes recalcitrant in the NMR intermediate exchange regime as the interface resonances are broadened beyond detection. Here, we determined the 19F low-populated bound-state pseudocontact shifts (PCSs) of mono- and di-fluorinated inhibitors of the BRM bromodomain using a highly-skewed protein/ligand ratio. The bound-state 19F PCSs were retrieved from 19F chemical exchange saturation transfer (CEST) in...
