Attachment of nitroxide spin labels to nucleic acids for EPR.

Abstract

In addition to X-ray, NMR, and FRET, electron paramagnetic resonance (EPR) can be applied to elucidate the structure of different macromolecular systems and determine local surroundings of paramagnetic centers in DNA and RNA. This technique permits structural characterization as well as dynamic structural changes of macromolecular systems. To do so, free… (More)
