Structure Determination of an Ag(I) -Mediated Cytosine-Cytosine Base Pair within DNA Duplex in Solution with (1) H/(15) N/(109) Ag NMR Spectroscopy.

Abstract

The structure of an Ag(I) -mediated cytosine-cytosine base pair, C-Ag(I) -C, was determined with NMR spectroscopy in solution. The observation of 1-bond (15) N-(109) Ag J-coupling ((1) J((15) N,(109) Ag): 83 and 84 Hz) recorded within the C-Ag(I) -C base pair evidenced the N3-Ag(I) -N3 linkage in C-Ag(I) -C. The triplet resonances of the N4 atoms in C-Ag(I… (More)
