Step Parameter Movies

 

Click on the links below to view animated gifs. Each gif starts out with the original 1KX5 nucleosome structure and is transformed slowly into a new structure with a certain subset of the basepair parameters changed to constant average values for protein-DNA complexes. The movies help highlight the sequence dependent functional significance of the various basepair parameters in the nucleosome structure.

 

Movie showing the original twist values for 1KX5 being replaced by the average twist value for P-DNA (34.2¡).
