Abstract
The detailed conformational features and dynamics of the naturally occurring deoxyribotrinucleoside diphosphates d-TpTpT and d-TpTpC have been investigated at 20°C and 80°C in aqueous solution by nuclear magnetic resonance spectroscopy. The observed NNR parameters indicate that the conformational properties of the trimers are very similar to those of the constituent dimers and monomers, i.e., the monomers and dimers conserve their intrinsic conformational features when they become incorporated into oligomers. Model building indicate that the distant shieldings can originate from spatial configurations in which the central nucleotidyl unit is bulged out and the ω′1ω1, ω′2ω2 occupy |g+g+, g+g+| domains.Keywords
