Conformational change of complement proteins C3 and C4 induced by methylamine: An X-ray scattering study
Analysis of X-ray scattering data from dilute solutions of the complement proteins C3, C4 and C5 yields the radii of gyration 4.5, 4.25 and 4.8 nm, and the maximum distances within the molecules (Dmax) of 18, 14.5 and 14 nm, respectively. The X-ray data of C4 are compatible with the scattering from one single triaxial body represented as an elliptic cylinder with the semiaxes 5.6 and 2.1 nm and a
