DBBP: database of binding pairs in protein-nucleic acid interactions
BMC Bioinformatics
|December 5, 2014
Summary
Researchers analyzed protein-nucleic acid interactions, developing the DBBP database to detail hydrogen bonds. This resource aids in understanding binding sites and predicting new ones computationally.
Area of Science:
- Structural Biology
- Bioinformatics
- Biochemistry
Background:
- Protein-nucleic acid interactions are crucial for biological functions.
- Existing databases offer structural data but lack detailed binding site information.
- Three-dimensional coordinates in structural data do not explicitly reveal binding interfaces.
Purpose of the Study:
- To analyze hydrogen bonding interactions between proteins and nucleic acids.
- To develop a comprehensive database of these binding interactions.
- To provide a valuable resource for computational prediction of binding sites.
Main Methods:
- Analysis of extensive structural data for protein-DNA and protein-RNA complexes.
- Development of the DataBase of Binding Pairs (DBBP).
- Extraction and cataloging of hydrogen bonds at atomic and residue levels.
Main Results:
- DBBP contains 44,955 hydrogen bonds for protein-DNA interactions.
- DBBP includes 77,947 hydrogen bonds for protein-RNA interactions.
- The database details hydrogen bonding interactions from atomic to residue levels.
Conclusions:
- Analyzing protein-nucleic acid complex structures yields crucial insights.
- DBBP offers detailed hydrogen bonding information, valuable for research.
- The database serves as a resource for developing computational methods to predict binding sites.

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...
