Folding and packing comparison between EcDHNA:NP and SaDHNA:NP. (A) Folding comparison between the two structures. (B) Packing comparison between the two structuers. In panel A, EcDHNA and SaDHNA are in magenta and cyan, respectively. In panel B, the two tetramers of EcDHNA are in magenta and red, and those of SaDHNA are in cyan and green. The illustration was made using MolScript  and Raster3D [21, 22].
