Abstract
19F NMR spectroscopy is a powerful tool for the study of the structures, dynamics, and interactions of proteins bearing cysteine residues chemically modified with a trifluoroacetone group (CYF residue). 19F NMR relaxation rates for the fluoromethyl group of CYF residues are sensitive to overall rotational tumbling of proteins, fast rotation about the CF3 methyl axis, as well as the internal motion of the CYF side chain. To develop a quantitative understanding of these various motional contri-butions, we used the model free approach to extend expressions for 19F- T2 NMR relaxation to include side chain motions for the CYF residue. We complemented the NMR studies with atomic views of methyl rotation and side chain motions using molecular dynamics simulations. This combined methodology allows for quantitative separation of the contributions of fast pico- to nanosecond dynamics from micro- to millisecond exchange processes to the 19F linewidth, and highlights the utility of the CYF residue as a sensitive reporter of side chain environment and dynamics in proteins.

Protein side chain dynamics is associated with protein stability, folding, and intermolecular interactions. Detailed dynamics information is crucial for the understanding of protein function and biochemical and biophysical properties, which can be obtained using NMR relaxation techniques. In this review, (13)C relaxation of methine, methylene and methyl groups with and without...
