MeCOM

MeCOM compares and analyzes metalloenzyme active sites to identify metal ion-centric structural and pharmacophore similarities for applications in enzyme design, function investigation, and inhibitor development.

Key Features:

• Metal Ion-Centric Active Site Recognition: Identifies and centers analysis on metal ion(s) within enzyme active sites.
• Three-Dimensional Superimposition: Performs 3D superimpositions of metalloenzyme active sites using α-carbon patterns or pharmacophore features.
• Active Site Feature Extraction: Automatically extracts key active site features for downstream comparison.
• Similarity Evaluation: Quantifies degrees of similarity to distinguish similar and dissimilar active sites.

Scientific Applications:

• Metalloenzyme de novo Design: Supports design of novel metalloenzymes by comparing active site similarities and differences.
• Function Investigation: Enables exploration of functional relationships between different metalloenzymes via active site comparison.
• Inhibitor Development: Assists identification of active site features relevant to inhibitor targeting.
• Protein Function Prediction and Drug Repurposing: Reveals functional insights from active site similarity that can inform protein function prediction and drug repurposing.
• Inhibitor Selectivity Investigation: Helps distinguish similar and dissimilar active sites to inform selective inhibitor development.
• Discovery of Novel Structural Associations: Reveals associations between structurally distinct metalloenzymes by analyzing active site similarities.

Methodology:

Recognition of metal ion(s) within enzyme active sites, extraction of active site features, and three-dimensional superimposition using α-carbon patterns or pharmacophore features to evaluate and quantify similarity degrees and to identify similar versus dissimilar active sites.
