Gd3+ Spin Labeling for Measuring Distances in Biomacromolecules: Why and How?

Feintuch, Akiva; Goldfarb, Daniella; Otting, Gottfried


Applications of distance measurements by pulse dipolar electron-paramagnetic resonance (PD-EPR) spectroscopy to structural biology are based on introducing spin labels (SLs) at well-defined locations in the biomacromolecule. The most commonly used SLs are nitroxyl radicals, but recently SLs based on high-spin Gd3 + (S = 7/2) complexes have been shown to be an attractive alternative for PD-EPR, particularly double electron-electron resonance (DEER), at spectrometer frequencies higher than 30...[Show more]
