title: A nuclear-Overhauser-enhancement study of the solution structure of a double-stranded DNA undecamer comprising a portion of the specific target site for the cyclic-AMP-receptor protein in the gal operon. Sequential resonance assignment.
abstract: A 500-MHz 1H-NMR study on a double-stranded non-self-complementary DNA undecamer comprising a portion of the specific target site for the cyclic AMP receptor protein in the gal operon is presented. Using pre-steady-state nuclear Overhauser effect (NOE) measurements, all exchangeable imino, non-exchangeable base, methyl, and H1', H2' and H2" sugar proton resonances are assigned in a sequential manner. In addition, some of the H3' sugar proton resonances are also assigned and some of the exchangeable amino proton resonances identified. The relative magnitudes of the intranucleotide and internucleotide NOEs are indicative of a right-handed B-type conformation for the duplex undecamer in solution.
