SAXS solution structure of YdaT. (a) Experimental SAXS data of YdaT (black) and the calculated curve (red) obtained from the best-fitting ensemble of ten conformers (χ2 = 1.684). (b) Superimposition of the ten conformers of the YdaT SAXS ensemble (black Cα traces) onto the YdaT crystal structure (cartoon representation coloured as in Fig. 2b). In the SAXS ensemble, the POU domains adopt different orientations relative to the C-terminal four-helix bundle due to the flexibility of the loop between the C- and N-terminal domains (residues 96–99). |
