Fig. 3. PTB RBD3 and RBD4 interdomain interactions. (A) Overlay of the 20 lowest energy structures of PTB RBD34 in complex with CUCUCU. RBD3 is in blue, RBD4 in green, the interdomain linker in red, and the RNA in yellow. (B) View of the most representative structure. The side chains contributing to the interdomain interaction are shown by black sticks and by black dots representing their surfaces.
