Figure 1From: PNImodeler: web server for inferring protein-binding nucleotides from sequence dataCriteria of protein binding nucleotides. If a nucleotide is involved in any of the protein-DNA interactions of 3 types (hydrogen bonds, water bridges and hydrophobic interactions), it is classified as a binding site. A nucleotide in a black background represents a protein-binding site and others represent non-binding sites.Back to article page
