Low microwave-amplitude ESR spectroscopy: measuring spin-relaxation interactions of moderately immobilized spin labels in proteins.

Journal of biochemical and biophysical methods - 31 Aug 2004

Abstract excerpt

Electron spin resonance (ESR) spectroscopy in combination with site-directed spin labeling (SDSL) is a powerful tool for determining protein structure, dynamics and interactions. We report here a method for determining interactions between spin labels and paramagnetic relaxation agents, which is performed under subsaturating conditions. The low microwave-field amplitude employed (h(1)<0.36 G) only requires...
