Figure 4
Experimental background-subtracted SAXS patterns (circles) measured from 2.5 mg ml−1 solution of cytochrome c with the 2 m camera and 0.3 m camera combined into one curve. Exposure time was about 1 s with an incident flux of ∼2 × 1013 photons s−1. The corresponding SAXS curve calculated from the known three-dimensional atomic structure of cytochrome c using the CRYSOL program (Svergun et al., 1995) is shown as a full line (calculation parameters: cytochrome c structure 1HRC from the Protein Data Bank, CRYSOL program used with 30 harmonics and other parameters set to defaults). The experimental and calculated results are in good agreement. |
