GlyMDB

GlyMDB integrates glycan microarray data with protein structural information to analyze glycan–protein interactions and interpret microarray fluorescence intensities.

Key Features:

• Data Integration: A searchable database contains 5203 glycan microarray samples sourced from the Consortium for Functional Glycomics for comparative analysis of protein–carbohydrate interactions.
• Visualization and Analysis Tools: Signal intensity graphs distinguish binder and non-binder classifications based on user-defined criteria to aid identification of glycan-binding motifs.
• Comparative Analysis: Fluorescence intensity data can be compared across different microarray samples to discern subtle differences in glycan–protein interactions.
• Protein Structure Linkage: Microarray data are linked to Protein Data Bank (PDB) structures via protein sequence-based BLAST searches that match to PDB entries containing glycans.
• User-Provided Data Analysis: The system accepts uploaded glycan microarray data and supports database query options and binder versus non-binder classification tools.
• Structural Visualization and Further Investigation: Links to structural visualization tools and modules on GlycanStructure.ORG enable exploration of glycan-binding sites and detailed glycan structures.

Scientific Applications:

• Protein–Carbohydrate Interaction Analysis: Enables analysis of protein–carbohydrate interactions underlying diverse biological processes.
• Structural Determinant Discovery: Supports discovery of structural determinants that promote glycan binding to glycan-binding proteins (GBPs).
• Domain-Specific Research Support: Facilitates research applications in immunology, cell biology, and disease pathology.

Methodology:

Integration of 5203 glycan microarray samples from the Consortium for Functional Glycomics with PDB structural data; protein sequence-based BLAST searches to match microarray proteins to PDB entries containing glycans; fluorescence intensity-based binder versus non-binder classification using user-defined criteria; comparative analysis across samples and links to GlycanStructure.ORG for structural visualization.
