Abstract

The folding of the RNA and their three-dimensional structure are areas of the great interest of biological and medical research. Besides X-ray, NMR and FRET, Electron Paramagnetic Resonance (EPR) can be applied to elucidate RNA's three-dimensional structure and also the dynamics of the system. Indeed, EPR spectroscopy has already shown to be a powerful technique to characterize the local surrounding of the paramagnetic center in proteins or oligonucleotides(1,2). Pulsed ELectron Double Resonance (PELDOR) enable us to measure long range distances between two nitroxides TPA(1) in DNA(1) and RNA(2) and TEMPA (2 and 2*)(3). The spinlabel was introduced during the solid-phase oligonucleotide synthesis on different nucleobases(4).
