    Notes: Summary A set of three 3D (1H, 13C, 15N) triple-resonance correlation experiments has been designed to provide H1′-H8 intraresidue sugar-to-base correlations in purines in an unambiguous and efficient manner. Together, the HsCsNb, HsCs(N)bCb, and HbNbCb experiments correlate the H1′ sugar proton to the H8 proton of the attached base by means of the {H1′, C1′, N9, C8, H8} heteronuclear scalar coupling network. The assignment strategy presented here allows for unambiguous H1′-H8 intraresidue correlations, provided that no two purines have both the same H1′ and C1′ chemical shifts and the same C8 and N9 chemical shifts. These experiments have yielded H1′-H8 intraresidue sugar-to-base correlations for all five guanosines in the [13C, 15N] isotopically labeled RNA duplex r(GGCGCUUGCGUC)2.

    Simultaneous acquisition of [13C,15N]- and [15N,15N]-separated 4D gradient-enhanced NOESY spectra in proteins (1994)

    Notes: Summary The simultaneous acquisition of a 4D gradient-enhanced and sensitivity-enhanced [13C,15N]/[15N,15N]-separated NOESY is presented for the 74-residue [13C,15N]-labeled N-terminal SH3 domain of mGrb2 complexed with a peptide gragment from mSOS-2 in 90% H2O. The method readily accommodates different 13C and 15N spectral widths, but requires that the same number of increments be collected for both 13C and 15N in the simultaneous dimension (F2). For purposes of display and analysis, the two 4D spectra can be deconvolved during the processing stage by the appropriate linear combination of separately stored FIDs. Compared to collecting each of these two 4D data sets separately, the presented method is a factor (2)1/2 more efficient in sensitivity per unit acquisition time. The interleaved nature of this method may also lead to improved peak registration between the two 4D spectra.
