WebUsing a combination of triple-resonance experiments and 3D 15 N-edited nuclear Overhauser effect spectroscopy (NOESY), we assigned about 85% of the backbone resonances of non-proline residues (Figure 2A). The majority of the unassigned residues are in the region from 35 to 51, possibly due to exchange broadening.
