Figure 4
Small-angle X-ray scattering (SAXS) analysis of the M2–1 RBD. (a) Raw scattering profile of the HRSV M2–1 RBD with the Guinier region shown in the inset. (b) Kratky plot suggesting the presence of a folded core with a flexible tail. (c) Distance distribution plot. (d) Ab initio shape reconstruction (grey) superimposed on the crystal structure of the HRSV M2–1 RBD (PDB entry 5noh; blue). The N- and C-termini of the protein are highlighted in green and red, respectively. |
