Structure of 4E-BP free in solution. (a) Experimental SAXS profile of 4E-BP (green dots) fitted by the scattering curves calculated with the program DAMMIF (yellow). Inset: Kratky plot [I(q)q2 versus q] with a plateau illustrating specifically the unfolded nature of 4E-BP. (b) Example of the most typical shape of 4E-BP, as obtained by DAMMIF, shown in two orientations rotated by 180°.
