The nonexchangeable base and sugar protons of the octanucleotide d(G-G-A-A-T-T-C-C) have been assigned by two-dimensional correlated (COSY) and nuclear Overhauser effect (NOESY) methods in aqueous solution. The assignments are based on distance connectivities of less than 4.5 A established from NOE effects between base and sugar protons on the same strand and occasionally between strands, as well as, coupling connectivities within the protons on each sugar ring. We observe the NOEs to exhibit directionality and are consistent with the d(G-G-A-A-T-T-C-C) duplex adopting a right-handed helix in solution. The relative magnitude of the NOEs between base and sugar H2' protons of the same and 5'-adjacent sugars characterizes the AATT segment to the B-helix type in solution.
