SAXS characteristics of GCEC. a Kratky plot analysis [71]. The intensity of scattering is plotted as I(s)/I(0)·s2 versus radius of scattering s. The curve representing GCEC SAXS data (blue line) does not have a maximum, and at higher s values reaches a plateau. Two additional curves are presented: for METC (IDP, green line) and for myoglobin (globular protein, orange line). b Gunier plot of GCEC SAXS data [71]. The experimental data (blue dots) shows a good fit to the calculated Gunier equation. It indicates monodispersity of GCEC in solution. c The pair distribution function p(r) of GCEC. The function is asymmetric, which indicates an elongated GCEC shape
