  1. Hydrogen bonds reported by HBPLUS [46] between pairs of atoms in the side-chains of amino acids and bases in the set of 210 protein-DNA complexes extracted from PDB were computed. Rows correspond to the hydrogen bond donor/acceptor atoms from the amino acids and columns to the hydrogen bond donor/acceptor atoms from bases (T, C, A, G) with their corresponding PDB atom codes. Each cell indicates the number of contacts found for a given pair of atoms.
