Peculiarities of interaction of porphyrins with tRNA at low ionic strength.

abstract：:Abstract Using high frequency antiphase NMR spectroscopy and computer simulations of the antiphase spectra, we studied the equlibria in the sugar conformations in the DNA duplex 11-mer containing the AAA tract surrounded by cytosines. We demonstrate that at the 3'-end of the A-tract, the sugar switches from the comm...
