Abstract
Recently, we discovered novel silver(I)-mediated cytosine-cytosine base pair (C-Ag(I)-C) in DNA duplexes. To understand the properties of these base pairs, we searched for a DNA sequence that can be used in NMR structure determination. After extensive sequence optimizations, a non-symmetric 15-base-paired DNA duplex with a single C-Ag(I)-C base pair flanked by 14 A-T base pairs was selected. In spite of its challenging length for NMR measurements (30 independent residues) with small sequence variation, we could assign most non-exchangeable protons (254 out of 270) and imino protons for structure determination.
