Sequence specific recognition of ligand-DNA complexes studied by NMR

Area of Science:

• Structural Biology
• Medicinal Chemistry
• Biochemistry

Background:

• Ligand-DNA interactions are crucial for understanding biological processes and drug development.
• An accelerated accumulation of detailed information on these interactions necessitates a synthesized review.

Purpose of the Study:

• To consolidate structure-based information on ligand-oligodeoxyribonucleotide (DON) complexes.
• To advance the understanding of ligand-DNA recognition principles.
• To support the rational design of DNA-binding ligands.

Main Methods:

• Focus on structure-based data from literature published since 1995.
• Emphasis on Nuclear Magnetic Resonance (NMR) structure elucidation.
• Analysis of sequence-specific recognition of binding motifs.

Main Results:

• Comprehensive list of DNA-binding ligands and their recognized DNA sequences.
• Identification of novel binding motifs in ligand molecules.
• Detailed discussion of structure-based ligand-oligodeoxyribonucleotide (DON) complexes.

Conclusions:

• NMR-elucidated structures provide key insights into sequence-specific ligand-DNA recognition.
• This review serves as a valuable resource for building a modeling database.
• Facilitates the rational design of novel DNA-binding ligands with desired properties.
