Combined NMR-SAXS model of the LptC-LptAm complex. (a) Representation of LptC-LptAm half complex. LptC and LptAm interact mainly through the formation of a continuous antiparallel β-sheet between the C-terminal β-strand of LptC and the N-terminus β-strand of LptAm. (b) Overlay of the backcalculated SAXS curve from the best energy NMR-SAXS model (magenta) with respect to the raw data (black). The chi-squared value is χ2 = 9.25. (c) Ribbon representation of the best NMR-SAXS LptC-LptAm complex fitted into the ab-inito envelope of the complex (wheat). In the lower panel the best NMR-SAXS structure is represented in cyan-red as a surface for comparison with the upper-panel SAXS envelope. LptC and LptAm molecules are shown in cyan and in red, respectively.
