A comparison of chemical shift sensitivity of trifluoromethyl tags: optimizing resolution in ¹⁹F NMR studies of proteins.

Abstract

The elucidation of distinct protein conformers or states by fluorine ((19)F) NMR requires fluorinated moieties whose chemical shifts are most sensitive to subtle changes in the local dielectric and magnetic shielding environment. In this study we evaluate the effective chemical shift dispersion of a number of thiol-reactive trifluoromethyl probes [i.e. 2… (More)
