Conformationally Restricted Isoindoline-Derived Spin Labels in Duplex DNA: Distances and Rotational Flexibility by Pulsed Electron-Electron Double Resonance Spectroscopy

Gophane, Dnyaneshwar B.; Endeward, Burkhard; Prisner, Thomas F.; Sigurdsson, Snorri (Wiley, 2014-10-08)

Three structurally related isoindoline-derived spin labels that have different mobilities were incorporated into duplex DNA to systematically study the effect of motion on orientation-dependent pulsed electron-electron double resonance (PELDOR) ...
Sterically shielded spin labels for in-cell EPR spectroscopy: Analysis of stability in reducing environment

Jagtap, A. P.; Krstic, I.; Kunjir, N. C.; Hänsel, R.; Prisner, Thomas F.; Sigurdsson, Snorri (Informa UK Limited, 2014-11-20)

Electron paramagnetic resonance (EPR) spectroscopy is a powerful and widely used technique for studying structure and dynamics of biomolecules under bio-orthogonal conditions. In-cell EPR is an emerging area in this field; however, it is hampered by ...
TEMPO-derived spin labels linked to the nucleobases adenine and cytosine for probing local structural perturbations in DNA by EPR spectroscopy

Gophane, Dnyaneshwar B; Sigurdsson, Snorri (Beilstein Institut, 2015-02-09)

Three 2´-deoxynucleosides containing semi-flexible spin labels, namely TA, UA and UC, were prepared and incorporated into deoxyoligonucleotides using the phosphoramidite method. All three nucleosides contain 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) ...
