BR187–385 is a monomer in solution. (a) The continuous distribution of sedimentation coefficients reveals a single population for the BR187–385 monomer with a sedimentation coefficient of 1.85 S. The averaged theoretical sedimentation coefficients calculated for the SAXS-derived BR187–385 monomer models are in agreement with the experimentally determined value. The averaged value and the standard deviation are in red and dotted red, respectively. (b) The theoretical scattering curve obtained for an ensemble of 18 BR187–385 monomer models (see also electronic supplementary material, figure S1) fits the SAXS profile of BR187–385 with a χ2-value of 0.58. The radius of gyration Rg obtained from the Guinier approximation was 22.7 ± 1.2 Å (mean ± s.d.). The distance distribution function p(r) gave Rg and Dmax values of 22.5 ± 2.0 Å and 77.0 ± 8.0 Å, respectively.
