Values in the table correspond to RMSD for all Cα atoms in Å.
a
These structures all display C2 symmetry.
b
Although twofold symmetry is preserved in the CTD and TMD, the overall C2 symmetry of the complex is disrupted due to a ∼25° bend between the two domains. As a result, the structures were determined without imposing any symmetry (C1).
