Details | Experimental small-angle X-ray scattering data were acquired at the beam line 4-2, SSRL, using incident radiation at the 8 keV and 1.25 m sample-to-detector distance. One-dimensional gas position-sensitive detector was used for data collection. EXPERIMENTAL NMR DATA used for structure refinement are THE SAME AS IN THE PDB DEPOSITION 1Y8B (citation 1). SAXS intensities OVER THE RANGE Q = 0.028 TO 0.780 A-1 were FITTED BY A supplementary MODULE as described in citation 2. |
