PRince

PRince analyzes structural features and physicochemical properties of protein-RNA interfaces to quantify molecular interactions and specificity in protein-RNA recognition.

Key Features:

• Input Requirements: Accepts a PDB file containing atomic coordinates for both protein and RNA chains and requires specification of chain identifiers for interacting entities.
• Interface Analysis: Estimates the size of protein-RNA interfaces by measuring solvent accessible surface area buried upon interaction.
• Property Calculation: Computes structural properties, physicochemical characteristics, and hydration features from molecular coordinates.
• Output Presentation: Provides calculated parameters in a tabular format.

Scientific Applications:

• Structural biology: Supplies quantitative interface metrics to support analysis of protein-RNA complex architecture.
• Drug discovery: Provides interface and physicochemical data relevant to targeting protein-RNA interactions.
• Molecular interaction analysis: Enables study of specificity and molecular recognition in protein-RNA complexes.

Methodology:

Parses PDB files, calculates changes in solvent accessible surface area, and extracts physicochemical properties from molecular structures.
