Figure 7. Solution structures of FPc and FP E244K.

Figure 7

  1. Experimental SAXS data (dark blue) from FPc and the calculated curve (red) from the rigid body model shown in panel (E).
  2. Experimental SAXS data (dark blue) from FP E244K and the calculated curve (red) from the rigid body model shown in panel (F).
  3. The distance distribution functions P(r) calculated from the data indicate Dmax values of 18 and 15 nm for FPc and FP E244K, respectively.
  4. The Rg‐normalized Kratky plot indicates that FPc has a compact core with flexible legs attached. FP E244K appears more globular and slightly less flexible. The dashed black lines indicate qRg = √(3) and I(q)/I(0)(qRg)2 ≈ 1.104, which is the theoretical maximum value for a globular shape. The FP E244K plot has a maximum much closer to this theoretical maximum compared to FPc.
  5. Ab initio model (transparent surface) and a representative rigid body model (cartoon) of FPc.
  6. Similar to panel (E), but based on data from FP E244K.
