Solution structure and dynamics of the specific complex between the KH3 and KH4 domains of FBP and the ssDNA FUSE element of c-myc Structures of the KH4-ssDNA (a and b) and KH3-ssDNA (c and d) portions of the FBP3/4-ssDNA complex Dynamics of the FBP3/4-ssDNA complex
The time scale and magnitude of the interdomain motions are described by an efective slow internal correlation time of 4.1 ns for the KH3 half of the complex and 3.6 ns for the KH4 half of the complex, and the two domains wobble independently in cones with a semi-angle of ~30 degrees. The overall FBP3/4-ssDNA complex has a rotational correlation time of 21.5 ns and a diffusion anisotropy of 1.85.
