Distance measurements between manganese(ii) and nitroxide spin-labels by DEER determine a binding site of Mn2+ in the HP92 loop of ribosomal RNA

Kaminker, Ilia; Bye, Morgan; Mendelman, Natanel; Gislason, Kristmann; Sigurdsson, Snorri; Goldfarb, Daniella (Royal Society of Chemistry (RSC), 2015)

Mn2+ localization in hairpin 92 of the 23S ribosomal RNA (HP92) was obtained using W-band (95 GHz) DEER (double electron-electron resonance) distance measurements between the Mn2+ ion and nitroxide spin labels on the RNA. It was found to be preferably ...
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) ...
