Arsenical probes are utilized for structural studies of proteins, with the ability to be attached to irregular loop regions and induce sizable pseudocontact shifts in protein NMR spectra through lanthanide-binding tags.
Arsenical probes enable structural studies of proteins. We report the first organoarsenic probes for nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) spectroscopy to study proteins in solutions. These probes can be attached to irregular loop regions. A lanthanide-binding tag induces sizable pseudocontact shifts in protein NMR spectra of a magnitude never observed for small paramagnetic probes before.
