Transformation of the SAXS curves for the crystallization system during the different steps of the crystallization process. (A) The SAXS curves related to different steps of the crystallization process. The red arrows in the small angle region indicate the interference peaks from the lipid/detergent smectic phase (curve designations are given in the legend; steps numbering is described in Fig. 1). (B) The peaks extracted from the SAXS curves (part A) by subtraction of the baseline. The curves are scaled to separate them vertically for better visualization. The black arrows “Lα1” and “Lα2” (shown in both A,B) indicate the lamellar peaks of the first and second order; the other black arrow “Lcryst 64 Å” indicates the peak from the local lamellar phase bonded with the protein surface, the spacing of this Lcryst is 64 Å. The arrow “68 Å” indicates the precursor of the Lcryst phase.
