A chemical approach for site-specific identification of NMR signals from protein side-chain NH₃⁺ groups forming intermolecular ion pairs in protein-nucleic acid complexes.

abstract：:HNCO/HNCACO type correlation experiments are an alternative for assignment of backbone resonances in extensively deuterated proteins in the solid-state, given the fact that line widths on the order of 14-17 Hz are achieved in the carbonyl dimension without the need of high power decoupling. The achieved resolution dem...

abstract：:Extensive resonance overlap exacerbates assignment of intrinsically disordered proteins (IDPs). This issue can be circumvented by utilizing (15)N, (13)C' and (1)H(N) spins, where the chemical shift dispersion is mainly dictated by the characteristics of consecutive amino acid residues. Especially (15)N and (13)C' spin...
