Fig 3. Comparison of the solution structure of PRC1-DD and the corresponding segments in crystal structure.

(a) Superimposition of ribbon representation of the PRC1-DD lowest-energy solution structure and crystal structure; H1 and H2 of the solution structure are colored yellow and orange, respectively, while H1 and H2 of the crystal structure are colored in cyan and blue, respectively; C and N tags signify C- and N-terminal ends, respectively. (c) Enlargement of the dotted box in (a). Figures were plotted using MATLAB, while the alignment was performed using CHIMERA.
