MetalS2

MetalS2 aligns Minimal Functional Sites (MFSs) of metal-binding biological macromolecules to compare local metal-binding environments independently of the overall protein fold.

Key Features:

• Independent structural alignment: Aligns MFSs without considering the global protein fold to focus on the local chemical environment around metal ions.
• Comparison across metals and nuclearity: Compares MFSs containing different metal ions and varying nuclearity (number of metal atoms) to identify structural relationships across diverse systems.
• Enhanced detection of structural similarities: Employs an alignment algorithm that has demonstrated superior performance in identifying structurally similar MFSs compared to existing protein structure comparison programs.

Scientific Applications:

• Investigate metal reactivity: Enables analysis of the local ligand environment and spatial arrangement to infer factors affecting metal chemical reactivity in metalloenzymes and metalloproteins.
• Explore functional conservation: Detects conserved structural motifs across unrelated proteins to study evolutionary relationships and functional adaptations of metal-binding sites.
• Facilitate drug design: Provides detailed structural information on MFSs to support rational design of molecules targeting metal-binding sites.

Methodology:

Analyzes 3D templates describing the local environment around metals within macromolecules and applies an alignment algorithm to uncover structural similarities independent of the larger protein structure.
