Summary
CapsidMaps is a new tool for visualizing protein interactions in viruses. It aids structural virology by analyzing capsid structures and comparing viral particles.
Area of Science:
- Structural virology
- Computational biology
- Biophysics
Background:
- Analyzing protein-protein interactions in viruses is complex due to numerous interfaces and residues.
- Existing methods struggle to fully visualize the extent of contacts within viral capsids.
Purpose of the Study:
- To introduce CapsidMaps, an interactive tool for structural analysis and visualization of viral protein-protein interactions.
- To enhance the study of viral capsid structures and quaternary interactions.
Main Methods:
- CapsidMaps was developed as an extension of the φ-ψ Explorer.
- The tool offers interactive analysis and visualization of protein contacts.
- It computes a similarity (S)-score for comparing quaternary interactions.
Main Results:
- Demonstrated the utility of CapsidMaps using analysis of a spherical virus.
- Showcased features for identifying solvent-exposed residues and potential antigenic epitopes.
- Highlighted the tool's capability to locate residues interacting with the viral genome.
Conclusions:
- CapsidMaps provides a valuable resource for the structural virology community.
- The tool facilitates detailed analysis of viral capsid structures, interactions, and functional regions.
- It is available as a free, web-based application within the VIPERdb Science Gateway.

77.0K
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

1.2K
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

15.0K
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...

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

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,...
