Figure 1

Experimental SAXS curves from the full-length M1 protein with gradually increasing pH: (a) 1 − pH 4.0; 2 − pH 5.2; 3 − pH 6.0; 4 − pH 6.4; 5 − pH 6.8. The curves are shifted along the ordinate by one logarithmic unit for better visualization. The red dashed line separates regions of scattering from the M1 self-assembles (to the left from the line), and from the individual M1 macromolecules (to the right from the line). (b) The Kratky plots of the all specimens (the data was normalized against the solute concentration). All symbols and numbering are the same as on the panel a.
