A Stacked rows extracted from five different HCACO experiments for seven residues of the HIPIP protein PioC. Each panel show a selected row of the HCACO experiment recorded with modified versions of the experiments, as presented in Fig. 1A and re-summarized here: a: standard pulse sequence; b: no C^α/C^β coupling; c: no C^α/C^β coupling & no IPAP; d: no C^α/C^β coupling & no IPAP & shorter H^α/C^α INEPT period; e: no C^α/C^β coupling & no IPAP & shorter H^α/C^α INEPT & shorter C^a/C' INEPT evolution. B Lowest energy NMR conformer of PioC (PDB ID: 6XYV). Residues shown in panels A are labeled and marked in green
