Area of Science:
- Biochemistry and Structural Biology
- Bioinformatics and Computational Biology
Background:
- Protein-carbohydrate interactions are crucial for numerous biological processes.
- Dysregulation of these interactions is implicated in various diseases.
Purpose of the Study:
- To introduce DIONYSUS, the first database specifically cataloging protein-carbohydrate interfaces.
- To provide comprehensive annotations including structural, chemical, and functional properties.
Main Methods:
- Development of a database integrating information on interaction nature, binding site composition, and biological function.
- Implementation of search functionalities based on protein sequence/structure and carbohydrate binding site properties.
- Inclusion of comparative analysis tools for interaction sites against known non-covalent interactions.
Main Results:
- DIONYSUS offers exhaustive data on protein-carbohydrate interfaces.

Protein-protein Interfaces
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...

Protein Networks

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,...

Protein Complexes with Interchangeable Parts
2.5K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.

Protein Organization
6.3K
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....
