SAXS data, primary structural parameters and overall shape characteristics. (a) Averaged SEC-SAXS profile of XIAP through the dimeric elution peak (black) and the corresponding fit against the data from the best-fitting HADDOCK model (see Section 2[link]; χ2 = 1.5 with no systematic deviation). (b) Ab initio bead-model reconstruction overlaid with the best-fitting HADDOCK model. The most probable ab initio model determined with P2 symmetry is shown. The resolution of the model was determined to be 34 ± 3 Å. (c) Distance distribution profile of XIAP. (d) Dimensionless Kratky plot. The typical peak position for globular proteins (x = 31/2, y = 1.1) is indicated.
