Conserved interdomain region in FnIII-3,4 of β4. (a) Molecular surface of the FnIII-3,4 structure coloured by the evolutionary conservation of the amino acids in the β4 sequences of 39 species calculated with the ConSurf server. The linker is shown in the conformation that yielded the best fit to the SAXS data. (b) Alignment of the sequences of the linker of nine species representative of the evolutionary variability. Positions are coloured according to the evolutionary conservation as in (a). A complete alignment of the sequences of the β4 FnIII-3,4 region of 39 species is shown in Supplementary Fig. S12. |
