摘要：

F marks the spot: We report a new technique for selectively labeling Trp side chains in proteins with 19F by using 3-β-indoleacrilic acid as an inhibitor of tryptophan biosynthesis. Our method finds useful application in the study of protein-protein or protein - ligand interactions (see figure) by means of 19F NMR spectroscopy.
