Sequence-specific recognition of DNA: assignment of nonexchangeable proton resonances in the consensus Pribnow promoter DNA sequence by two-dimensional NMR

Abstract
The resonances of most of the nonexchangeable protons of both + and - strands of the consensus Pribnow dodecamer d( CGTTATAATGCG ) have been assigned by two-dimensional nuclear magnetic resonance methods. Application of the two-dimensional nuclear Overhauser effect ( NOESY ) sequential connectivity method, combined with two-dimensional autocorrelated ( COSY ) spectra to reveal scalar-coupled protons, results in assignment of virtually all of the base and sugar protons, except the sugar C5 protons which are inadequately resolved. Analysis of the nuclear Overhauser data indicates that the helix assumes a fairly uniform B form conformation.
