HBAT

HBAT identifies potential hydrogen bonds, halogen bonds, and non-canonical weak interactions in macromolecular structures (PDB format) to characterize interaction networks and geometrical properties.

Key Features:

• Automation of Interaction Analysis: Identifies potential hydrogen bonds, halogen bonds, and non-canonical interactions using specific geometrical criteria.
• Output Generation: Produces MSOFFICE Excel-compatible output files for downstream statistical analyses.
• Comprehensive Reporting: Generates frequency tables, geometry distribution tables, and lists of furcations.
• 2D Visualization of Interaction Networks: Creates 2D visualizations of hydrogen bond networks using Graphviz to represent cooperativity and anticooperativity geometry.
• Post-Docking Interaction Analysis: Analyzes interactions between PDB structures and docked ligands/poses provided in SDF format.
• Implementation: Implemented using PERL and TK programming languages.

Scientific Applications:

• Active Site Interaction Analysis: Identifies and characterizes interactions within active sites to inform interpretation of enzyme mechanisms and ligand binding.
• Structure-Based Drug Design: Characterizes interaction networks and geometrical properties to support ligand optimization and binding assessment.
• Molecular Dynamics Simulations: Assesses weak interaction patterns to support analysis and refinement of simulation models.

Methodology:

Automated identification based on specified geometrical criteria; generation of MSOFFICE Excel-compatible output, frequency tables, geometry distribution tables, and lists of furcations; 2D network visualization via Graphviz; support for PDB and SDF formats; implemented in PERL and TK.
