DNA Binding Protein

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Proteins that non-covalently interact with deoxyribonucleic acid as a result of intermolecular physical forces and spatial complementarity. Many genetic regulatory DNA binding proteins bind to double- or single-stranded DNA in a sequence-specific manner and share common structural motifs such as the zinc-finger, helix-turn-helix, and leucine zipper.
