VoroContacts

VoroContacts computes contact surface areas (CSAs) and solvent accessible surface areas (SASAs) of proteins, nucleic acids, and their complexes at atomic resolution to analyze molecular interaction interfaces.

Key Features:

• Atomic-resolution surface calculations: Computes CSAs and SASAs for proteins, nucleic acids, and their complexes at atomic resolution.
• Voronoi tessellation-based analysis: Applies Voronoi tessellation to 3D structures represented as collections of atomic balls to derive contact areas.
• Advanced contact filtering: Filters interatomic contacts by contact type, contact surface area, interatomic distance, and sequence separation between residues.
• Batch processing via Voronota: Can be used within the standalone Voronota package to support batch processing of large datasets.

Scientific Applications:

• Protein–protein interactions: Identifies and quantifies binding interfaces and interaction hotspots through CSA and SASA analysis.
• Nucleic acid structural studies: Examines structural features and interaction surfaces of nucleic acids and their complexes.
• Drug design and development: Maps potential binding sites on target molecules by detailed surface area analysis.

Methodology:

VoroContacts applies Voronoi tessellation to 3D structures represented as collections of atomic balls, partitioning space around atomic centers to compute contact surface areas and solvent accessible surface areas.
