*Dihedral angle constraints were generated by TALOS based on Cα and Cβ chemical shifts.
†Average rms deviation to the mean structure in each structural region was calculated among 10 refined structures. The total AMBER energies for NTD, RP1, RP2, and CTD are −3,556 ± 34, −3,834 ± 41, −3,220 ± 29 and −4,231 ± 25 kcal/mol, respectively.
