Figure 3
The experimental SAXS curve of α-crustacyanin with error bars (black) combining regimes of low and high scattering angles was collected at station 2.1 of the Daresbury SRS according to standard procedures (Grossmann, 2002) using sample-to-detector distances of 1 m and 4.5 m. SAXS curve of α-crustacyanin compared with the theoretical scattering of (a) the rigid-body model with lowest χ value (pink), (b) the EM-derived model (green) and (c) eight β-crustacyanin dimers extracted from the crystal lattice of 1gka
(blue). In each case the model is shown as a surface representation. |
