Figure 1.

(A) An overlay of the six protein molecules in the X-ray structure of the free Fox-1 RRM. (B) An overlay of the Fox-1 RRM in X-ray (blue) and NMR (red) structures used in the MD simulations. The two differing segments are indicated by a black rectangle (α2 helix) and a circle (β3 sheet). The secondary structure of the proteins and the chain termini are labeled. The position of the RNA backbone in a formed complex is traced in brown.
