Snapshot of web-based interface for analyzing global properties of HTH-DNA interactions. Shown is a Heatmap of atomic contact frequencies averaged across all structures in the database. For any given residue position pair, one in the protein and one in the DNA (left, highlighted in red), users can inspect atomic contact frequencies across all atom types at a user-defined separation distance (right)
