Abstract: The structures of triple helices alpha dT6.beta dAn.beta dTn, alpha dT12.beta dAn.beta dTn, alpha dC12+.beta dGn.beta dCn, and alpha dC12+.beta rGn.beta rCn have been studied by Fourier transform infrared spectroscopy, Raman spectroscopy, and molecular mechanics calculations. The sugar conformations in these triplexes have been determined by vibrational spectroscopy. Our results show the existence of only S-type sugars in the alpha dT12.beta dAn.beta dTn triple helix. Both S- and N-type sugar infrared and Rama…
