pepinfo

pepinfo analyzes and plots physicochemical properties of amino acids across protein sequences within the EMBOSS suite to aid interpretation of hydrophobicity, charge, and residue size distributions.

Key Features:

• Amino Acid Property Plotting: Generates parallel plots of physicochemical properties for residues across protein sequences.
• Property Types: Computes and visualizes hydrophobicity, charge, and residue size distributions.
• Comparative Sequence Analysis: Highlights differences in physicochemical properties between protein sequences for characterization.
• EMBOSS Integration: Implements functionality as part of the EMBOSS suite and uses its computational libraries.

Scientific Applications:

• Protein Structure Analysis: Visualization of residue properties to support inference of structural motifs and functional regions.
• Sequence Characterization: Comparative analysis of physicochemical profiles to identify sequence-specific features.
• Molecular Biology Research: Supports hypothesis generation about protein function based on amino acid property patterns.

Methodology:

Implements calculations and plotting routines using EMBOSS's C programming libraries to compute residue-level physicochemical properties and render parallel property plots.
