To better understand the conformational impact by the knob and hole mutations, we combined size-exclusion chromatography (SEC), differential scanning calorimetry (DSC), and hydrogen-deuterium exchange mass spectrometry (H/D exchange MS), to characterize the global and peptide-level conformational changes.
