Fig. 5.

Representative structures showing interactions between crowder proteins and the Drew-Dickerson dodecamer (a, b) and the GC-rich DNA (c, d). Specific interactions are shown between lysines and the DNA phosphate groups (A), between a threonine residue and a ribose sugar (b), between protonated glutamate and a phosphate (c), and between asparagine and the phosphate (d). Interacting residues are shown in licorice (DNA) and ball-and-stick (protein) representation. The chosen structures have minimal distances between the DNA and the protein
