| 1 | 2D NOESY | Four milligrams of HgTX1 were dissolved in 0.5 ml mixture of H2O and D2O in a 9:1 ratio (v/v). The pH value of the HgTX1 solution was 3.0 uncorrected for isotope effects. Amide proton exchange rate was determined after lyophilization and dissolution in 100% D2O | 3.0 | 300 | ||||
| 2 | DQF-COSY | Four milligrams of HgTX1 were dissolved in 0.5 ml mixture of H2O and D2O in a 9:1 ratio (v/v). The pH value of the HgTX1 solution was 3.0 uncorrected for isotope effects. Amide proton exchange rate was determined after lyophilization and dissolution in 100% D2O | 3.0 | 300 | ||||
| 3 | 2D-TOCSY | Four milligrams of HgTX1 were dissolved in 0.5 ml mixture of H2O and D2O in a 9:1 ratio (v/v). The pH value of the HgTX1 solution was 3.0 uncorrected for isotope effects. Amide proton exchange rate was determined after lyophilization and dissolution in 100% D2O | 3.0 | 300 | ||||
