Reveal

Reveal predicts active sites in polypeptide chains by modeling hydrophobic cores and comparing observed hydrophobicity distributions with an idealized fuzzy oil-drop model to identify functionally relevant regions.

Key Features:

• Three-Dimensional Gauss Function Representation: Employs a three-dimensional Gauss function to model the hydrophobic core of proteins.
• Fuzzy Oil-Drop Model Discrepancy Analysis: Assesses discrepancies between the idealized fuzzy oil-drop model and observed hydrophobicity distributions, with attention to ligand-binding and functional regions.
• Hydrophobicity Distribution Profiling: Profiles differences between idealized and actual hydrophobicity distributions along polypeptide chains to characterize structure-function relationships.
• Fragment Specificity Evaluation: Evaluates the specificity of polypeptide chain fragments regarding their biological functions and roles in active-site formation.
• Comparative Scale for Ligand-Binding Sites: Computes a comparative scale for comparing proteins based on characteristics of their ligand-binding sites.

Scientific Applications:

• Functional Site Identification: Supports identification and characterization of ligand-binding and active sites within proteins.
• Enzyme Mechanism Analysis: Aids analysis of enzyme mechanisms by relating deviations in hydrophobic core distribution to catalytic regions.
• Drug Design and Ligand Interaction Studies: Informs drug design by comparing ligand-binding site properties across proteins to evaluate interaction-relevant features.
• Protein Engineering: Guides protein engineering by highlighting chain fragments that contribute to binding and biological activity.

Methodology:

Model the hydrophobic core using a three-dimensional Gauss function; compare observed hydrophobicity distributions to an idealized fuzzy oil-drop model to assess discrepancies; profile hydrophobicity differences along polypeptide chains; evaluate fragment-specificity; and compute a comparative scale for ligand-binding sites.
