Abstract:

19F nucleus has unique properties, such as that it is a 1/2 spin; natural abundance is 100%, having comparable sensitivity as 1H; chemical shift dispersion is large and ultra sensitive to the environment; most biological samples do not contain 19F, such that there is no interference background signal, etc. These properties make 19F NMR an attractive approach to study biological systems. 19F NMR has wide applications in magnetic resonance imaging, pharmacology chemistry and studies of biomacromolecules. There are many reviews on these topics. Here we will focus on the applications of 19F NMR in protein studies, including 19F labeling methods, protein structure and dynamics characterization, protein folding, protein-drug interactions and in-cell protein NMR.

Key words: 19F NMR, protein structure, protein dynamics, drug recognition, in-cell NMR
