BetaVoid

BetaVoid identifies and analyzes molecular voids on both the van der Waals surface and the Lee-Richards (solvent accessible) surface to compute geometrical properties relevant to molecular function.

Key Features:

• Analytic approach: Uses the Voronoi diagram of atoms and the beta-complex to detect and measure molecular voids without point-sampling.
• Surface support: Identifies voids on the van der Waals surface and the Lee-Richards (solvent accessible) surface.
• Geometrical and topological quantification: Computes volume, area, boundary area, and topology of voids.
• Mathematical guarantees: Algorithmic correctness and efficiency are mathematically proven.
• Experimental verification: Methodology has been experimentally verified for reliability and accuracy.
• Benchmark performance: Demonstrated superiority over VOIDOO and CASTp in comparative benchmarks.

Scientific Applications:

• Structural biology: Characterizes external molecular structure and voids relevant to structure–function relationships.
• Drug design: Identifies and quantifies potential binding sites for ligand design and optimization.
• Molecular dynamics: Analyzes void properties and their changes in dynamic simulations.
• Binding site identification: Detects cavities and voids that can serve as candidate binding sites.
• Protein–ligand interaction analysis: Provides geometric measures that inform protein–ligand recognition and interaction studies.

Methodology:

Constructs a Voronoi diagram from atomic positions, forms the beta-complex, and computes void identification and mass properties such as volume and boundary area.
