Validation of the biological unit by SAXS. (A) The parabolic nature of the Kratky plot at low values of q indicates that Csa3 is well folded. (B) The solution dimer corresponds to the crystallographic dimer present in a single asymmetric unit. The observed scattering curve of Csa3 (black) was compared with hypothetical scattering curves for the asymmetric unit (red), a potential monomer (light blue), and four alternative dimers (blue, violet, orange and green). Only the hypothetical scattering curve for the dimer corresponding to the crystallographic asymmetric unit agrees well with the observed scattering.
