pyScoMotif: 3D protein structural motif detection and comparison

pyScoMotif identifies similar three-dimensional structural motifs across large protein structure datasets by detecting conserved geometrical arrangements of amino acid residues.

Key Features:

• 3D Motif Detection: Detects structural motifs based on spatial geometry of protein residues to identify conserved arrangements.
• Flexible Search Criteria: Supports exact motif matching and mutated motifs with position-specific residue substitutions.
• Scalable Computation: Executes on diverse computational environments, including local machines and compute clusters.

Scientific Applications:

• Catalytic Site Identification: Identifies catalytic sites to characterize enzyme function and support drug design.
• Drug Target Discovery: Detects binding-region motifs to aid identification of potential therapeutic targets.
• Structural Conservation Analysis: Compares conserved structural features across proteins to assess evolutionary and functional relationships.

Methodology:

Analyzes protein structures to extract residue coordinates, evaluates spatial geometrical relationships among residues, and matches motif patterns across datasets using defined geometric constraints and optional position-specific substitutions.
