Superimpose

Superimpose performs structural similarity searches using three-dimensional (3D) structure-based methods to identify similarities among small molecules, protein binding sites, and whole proteins.

Key Features:

• Algorithm Implementation: Incorporates a variety of algorithms tailored to assess structural similarity across different molecular scales.
• Three-dimensional (3D) methods: Prioritizes 3D structure-based methods for detection of nuanced structural similarities not apparent from sequence alone.
• Database Integration: Provides access to multiple databases to enable searches against extensive collections of molecular structures.
• Visual Assessment Tools: Offers visual assessment capabilities for evaluating identified structural similarities.

Scientific Applications:

• Drug Discovery and Development: Enables structure-based in silico screening of drug-like compounds and identification of scaffold-hopping molecules with similar pharmacological potential.
• Functional Analysis of Proteins: Supports identification of structurally similar binding sites to inform analyses of protein function and molecular interactions.
• Protein Structure Comparison: Detects structurally similar proteins to identify analogous folds and examine backbone topology differences for evolutionary and structural biology studies.

Methodology:

Performs computationally intensive similarity searches, prioritizes three-dimensional (3D) structure-based methods, and integrates multiple algorithms and databases.
