Summary
Q-BioLiP enhances protein-ligand interaction studies by utilizing quaternary structures, addressing limitations of previous resources like BioLiP. This new database offers improved accuracy for various biomolecular interactions.
Area of Science:
- Biochemistry
- Structural Biology
- Bioinformatics
Background:
- BioLiP is a widely used resource for protein-ligand interactions since 2013.
- Existing resources like BioLiP primarily use tertiary structures, which is insufficient for interactions involving multiple protein chains (quaternary structures).
Purpose of the Study:
- To develop Q-BioLiP, a comprehensive database for protein-ligand interactions based on quaternary structures.
- To address the limitations of previous resources by incorporating quaternary structure information and improving interaction modeling.
Main Methods:
- Developed Q-BioLiP by representing protein structures as quaternary structures.
- Integrated proper pairing of DNA/RNA chains.
- Included both experimental and predicted binding affinities.
- Retained biologically relevant and irrelevant interactions.
- Created a novel quaternary structure-based algorithm for protein-ligand complex modeling.
Main Results:
- Q-BioLiP provides a resource for quaternary structure-based protein-ligand interactions.
- The database includes diverse interaction types: protein-small molecule, protein-metal ion, protein-peptide, protein-protein, protein-DNA/RNA, and RNA-small molecule.
- Offers both experimental and predicted binding affinities.
Conclusions:
- Q-BioLiP is a valuable resource for studying complex biomolecular interactions.
- The use of quaternary structures enhances the accuracy and scope of protein-ligand interaction analysis.
- Q-BioLiP is freely available for research use.

Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

12.5K
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...

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...

6.4K
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence....

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,...
