SAXS profiles of MurD and Hef-IDR. (a) Pink circles indicate experimental SAXS profile of MurD. Green and blue lines correspond to SAXS profiles calculated with its crystal (PDB code: 1e0d.pdb) and deformed structures by normal mode analysis (NMA), respectively. (b) Blue circles, experimental SAXS profile of Hef-IDR. Red line, ensemble-averaged profile of five representative structures. Inset, SAXS profiles of representative structures 1 (light blue), 2 (pink), 3 (light green), 4 (yellow) and 5 (black). This figure is prepared by the usage of IGOR Pro 6.34A (https://www.wavemetrics.com/forum/news-and-announcements/igor-634a-now-shipping).
