ProteinTools

ProteinTools performs structural analyses of protein three-dimensional coordinates to identify hydrophobic clusters, hydrogen bond networks, salt bridges, and contact maps for experimental characterization and computational assessment of protein structures.

Key Features:

• Modular framework: Integrates four distinct applications for consolidated structural analyses.
• Hydrophobic cluster identification: Detects hydrophobic clusters within protein structures.
• Hydrogen bond network identification: Identifies hydrogen bond networks between residues.
• Salt bridge identification: Detects salt bridges formed by charged residues.
• Contact map generation: Computes residue–residue contact maps representing tertiary interactions.
• Input formats: Accepts PDB identifiers and uploaded protein structure files.

Scientific Applications:

• Experimental structure characterization: Supports analysis of experimentally determined protein structures for interaction and stability features.
• Computational structure assessment: Assists evaluation of predicted protein structures by mapping contacts and interaction networks.
• Interaction and stability analysis: Characterizes intra-protein hydrophobic, hydrogen-bond, and electrostatic interactions relevant to stability and function.
• Topology and interface analysis: Uses contact maps to analyze tertiary/quaternary topology and residue–residue interfaces.

Methodology:

Performs computational identification of hydrophobic clusters, hydrogen bond networks, salt bridges, and computes contact maps from input PDB identifiers or uploaded protein structure files.
