RMSD and Rg of the basic region of each monomer for 50 ns of simulation time. (A) The RMSD and (B) the Rg behavior of all dimers. The minimized structures (t = 0 ns) were taken as a reference. The upper images represent the homodimers (TWI_A and TWI_B) and the bottom images correspond to the heterodimers (E47 and TWI). Å – angstrom (10-10 m);ns – nanoseconds (10-9 s).
