| pubmed-article:1772434 | pubmed:abstractText | The conformation of the decanucleotide duplex d(GGTAATTACC)2 has been investigated in solution by one- and two-dimensional proton NMR spectroscopy. Intra- and inter-nucleotide two-dimensional nuclear Overhauser enhancement data, recorded at mixing times between 15 and 250 ms, reveal a right-handed B-DNA structure. The data also show that the A-T basepairs of the TAATTA tract are highly propeller twisted and the minor groove is particularly narrow. | lld:pubmed |
