Accuracy in Action: Leading Lectin-Glycan Interaction Predictive Models

At CD BioGlyco, our Glycoinformatics-assisted Glycan-Molecular Interaction Analysis Service combines the latest bioinformatics, structural biology, and machine learning methods to analyze and predict interactions between glycans and molecules. As one of the core services of this service, our lectin-glycan interaction predictive modeling service integrates advanced computational biology and artificial intelligence technology services to help clients accurately predict and simulate the interaction between lectin and glycan. This service not only helps clients understand the mechanisms of these interactions at the molecular level, but also provides strong support for areas such as drug development, disease research, and new material design.

Data collection and pre-processing

Data collection: We collect structural, sequence, and functional data on known lectins and glycans from multiple sources to ensure data quality and consistency.

Standardization: We standardize the data, such as unification of coordinate systems, standardization of residue numbers, etc.

Protein-ligand interaction profiler (PLIP) feature generation

Interaction site identification: We use the PLIP tool to identify potential interaction sites between lectins and glycans.

Feature extraction: We extract key features from interaction sites, such as hydrogen bonds, hydrophobic interactions, ionic bonds, etc.

3D pocket identification

Pocket identification algorithms: We use three-dimensional pocket identification algorithms, such as FPocket or CASTp, to identify potential binding pockets on the lectin surface.

Pocket characterization analysis: We analyze pocket characteristics such as size, shape, charge distribution, etc. to evaluate their binding potential to glycans.

3D pocket feature generation

Pocket feature extraction: We extract key features from the identified three-dimensional pockets, such as the geometric features of the pocket, amino acid composition, electrostatic potential energy, etc.

Feature encoding: We encode the extracted features to facilitate subsequent machine learning algorithm processing.

Binding site residue characteristics

Residue analysis: We analyze the amino acid residue properties of the lectin binding site, such as hydrophobicity, charge, hydrogen bonding ability, etc.

Conservation analysis: We compare the binding site residues between different lectins and analyze their conservation during evolution.

One-versus-all statistical associations

One-to-many statistical analysis: We perform a statistical analysis of each lectin with all its possible binding glycans to identify significant features that bind to specific glycans.

Correlation analysis: We use correlation analysis methods (such as the Chi-square test and Fisher's exact test) to evaluate the degree of association between features and glycan binding.

One-versus-all predictive modeling

Predictive model construction: We construct independent prediction models for each lectin to predict its binding probability to different glycans.

Model training and optimization: We use machine learning algorithms to train prediction models and optimize model performance through cross-validation and other methods.

Glycan recognition similarity analysis

Glycan recognition similarity assessment: We analyze the similarity in recognition of glycans by different lectins to reveal commonalities and differences between them.

Cluster analysis: We group lectins using a clustering algorithm to identify lectin families with similar glycan recognition properties.

Determinants of fine specificity for αNeuAc glycans

Study of the fine specificity of specific glycans: We further study the fine specificity of lectin binding to αNeuAc-containing glycans.

Key feature identification: We identify key features that bind to αNeuAc glycans, such as specific amino acid residues and pocket shapes.

Mechanism analysis: We use structural biology and computational simulation methods to analyze the molecular mechanism of the binding of lectins to αNeuAc glycans, providing new ideas for drug design, disease research, and other fields.
