Analysis of protein-DNA interactions observed in the MD simulation of Dre/rox (a) Projection of hydrogen bond interactions spotted in the last frame of the Dre/rox MD trajectory. The base-specific interactions with the minor groove are labeled with an asterisk (*). Hashes (#) denote the interactions with the DNA major groove. Nucplot was used to generate the image. (b) Detailed view of interactions observed in the PDIBJ area of the Dre/rox complex based on MD simulations. The specificity-determining residues are highlighted with a yellow box. Hydrogen bonds are shown in black dashed lines and van der Waals interactions in dotted spheres. Pymol was used to generate the image (version 2.1, https://pymol.org/).
