Representation of the superhelical pitches and changes of the distances in the DNA-free and DNA-bound systems.

<p>(A) The cartoon representation of 11.5 TAL repeats and the DNA. The superhelical pitch of dHax3 is assessed by the distance between the Cα atoms of G303 (Gly303) and G675 (Gly675) (left), and the pitch of DNA by the distance between the C3′ atoms of 1dC and 12dT (right). (B) The distance change versus simulation time (solid line) and the value from crystal structure (dotted line) in the DNA-free system. (C) The distance change versus simulation time (solid line) and the value from crystal structure (dotted line) in the DNA-bound system.
