3D-e-Chem-VM

3D-e-Chem-VM integrates cheminformatics and structural bioinformatics tools to analyze protein–ligand interactions and perform structure-based chemical biology analyses.

Key Features:

• Integrated Structural Bioinformatics Tools: Combines multiple cheminformatics and bioinformatics software libraries for analysis and visualization of protein–ligand structural data.
• Proteome-Scale Database Integration: Connects to structural and pharmacological databases including ChEMBLdb, the Protein Data Bank (PDB), GPCRdb, and KLIFS.
• Virtual Ligand Screening: Includes Chemdb4VS for structure-based virtual screening of candidate ligands against protein targets.
• Ligand Metabolism Prediction: Incorporates SyGMa to predict ligand metabolism based on chemical structure.
• Protein Binding Site Comparison: Uses KRIPOdb for structure-based comparison of protein binding sites and identification of bioisosteric replacements.

Scientific Applications:

• Structure-Based Drug Discovery: Supports identification and optimization of candidate ligands through virtual screening and structural analysis.
• Protein–Ligand Interaction Analysis: Enables investigation of molecular interaction patterns between proteins and small molecules.
• Targeted Protein Family Studies: Facilitates structural analysis of specific protein families such as G protein-coupled receptors and protein kinases.

Methodology:

The platform integrates structural datasets and cheminformatics tools within a workflow environment that accesses databases such as ChEMBLdb and PDB, performs virtual ligand screening with Chemdb4VS, predicts ligand metabolism with SyGMa, and compares protein binding sites using KRIPOdb.
