FIGURE 3.
SAXS data collected for BMP-7 complex. A, x-ray scattering profile of BMP-7 complex showing intensity as a function of q (gray triangles) and Gnom fit to the data (black line). Inset, Guinier plot showing Rg of 4.8 nm. B, P(r) plot showing Dmax of 16 nm. C, Kratky plot showing profile typical of a folded protein. D, plateau in the Porod-Debye plot indicative of a non-flexible protein. E, ab initio models generated from SAXS data using GASBOR with 2-fold symmetry (blue); the averaged model is shown along with three representative models.
