SAXS analysis and low resolution solution structure of wild-type gp5 and gp5-C313S.
A, x-ray scattering profiles of wild-type gp5 and gp5-C313S are shown. Inset, small angle data and Guinier plots of wild-type gp5 and gp5-C313S are shown. B, shown is distance distribution function p(r) of wild-type gp5 (gray) and gp5-C313S (black) with Dmax values of 80 and 104 Å, respectively. p(r) was obtained using the computer program GNOM (34) and served as an alternative measure for Rg and the maximum dimension of the measured particle. C, the corresponding ab initio model of gp5 was obtained using the computer program GASBOR (37).
