pyKVFinder

pyKVFinder detects and characterizes cavities within biomolecular structures, quantifying volume, area, depth, and hydropathy to support structural biology, drug design, and supramolecular design.

Key Features:

• Efficient Cavity Detection: Identifies cavities within biomolecular structures rapidly and accurately.
• Quantitative Cavity Properties: Computes cavity volume, area, depth, and hydropathy.
• NumPy Data Storage: Stores computed cavity properties in NumPy ndarrays.
• Interoperability with Scientific Libraries: Integrates with matplotlib, NGL Viewer, SciPy, and Jupyter notebooks for visualization, molecular graphics, computation, and interactive workflows.
• Comparative Site Analysis: Identifies and compares the ADRP substrate-binding site of SARS-CoV-2 with homologous proteins.
• Automated Pipeline Compatibility: Compatible with automated pipelines for high-throughput analyses in structural biology.
• Supramolecular Cavity Evaluation: Evaluated for characterization of supramolecular cavities and compared against Fpocket.

Scientific Applications:

• Structural Biology: Analysis of cavity-mediated biomolecular interactions.
• Drug Design: Identification and characterization of ligand-binding sites such as the ADRP substrate-binding site in SARS-CoV-2.
• Supramolecular Design: Characterization of cavities to inform rational design of supramolecular cages.
• High-Throughput Structural Analysis: Integration into automated pipelines for large-scale cavity analyses.
• Data Science and Scripting Workflows: Enables scripted and reproducible analyses via NumPy, SciPy, matplotlib, NGL Viewer, and Jupyter notebooks.

Methodology:

Implemented in Python, pyKVFinder computes cavity volume, area, depth, and hydropathy and stores results in NumPy ndarrays.
