Triple resоnаnce experiments аre used tо perfоrm sequentiаl assignment of protein backbone atoms. The HNCACB experiment correlates the amide 1H-15N chemical shifts of one amino acid to the Ca and Cb chemical shifts of the same (intra) and the previous (inter) amino acid. The nature of the NMR pulse sequence is such that: (a) the “intra” signals typically have significantly higher intensity than the “inter” signals and (b) Ca and Cb signals have opposite phases. Another experiment, the CBCA(CO)NH, is also acquired to eliminate any ambiguities between “intra” and “inter” signals, as it correlates the amide 1H-15N chemical shifts of one amino acid to the Ca and Cb chemical shifts of only the previous (inter) amino acid. In the latter case, both the Ca and Cb signals have the same phase. A set of pairs of HNCACB (shown in black outline) and CBCA(CO)NH (shown in red outline) strips is shown below for a polypeptide stretch of a protein with sequence P-D-A-S-V-P. The vertical axis scale and units is common to all sets of strips. Note that prolines lack an amide 1H-15N and thus only four pairs of strips are displayed. With the help of the chemical shift table provided below, match each pair of strips, numbered 1-4, to each of D, A, S and V in the sequence (10 points)
