(a–c) Reconstructed SAXS envelopes and representative candidate structures from simulated annealing in (a) FM50, (b) NMF50, and (c) DMF50. Insulin chain A, chain B, and residues B11–B17 in the simulated structures are marked in purple, cornflower blue, and red, respectively. The scattering profiles and p(r) functions of the SAXS envelope and candidate structure are shown for comparison. The minor differences between the SAXS envelopes and representative structures were attributed to residues B24–B30. To see this figure in color, go online.
