BAlaS

BAlaS performs computational alanine-scanning mutagenesis to estimate per-residue energetic contributions to molecular interactions such as protein–protein binding using BudeAlaScan.

Key Features:

• Computational alanine-scanning mutagenesis (CASM): Performs CASM to evaluate the energetic effect of substituting individual residues with alanine.
• BudeAlaScan integration: Uses BudeAlaScan for the underlying energetic calculations.
• Per-residue energetic reporting: Produces quantitative per-residue energetic contributions for analyzed molecular interactions.
• Results visualization: Provides immediate visualization of computed per-residue energetic changes for inspected structural data.

Scientific Applications:

• Interface hotspot identification: Identifies energetically important residues in protein–protein interfaces.
• Guiding mutagenesis experiments: Prioritizes residues for alanine-scanning and site-directed mutagenesis by predicting energetic impact.
• Drug discovery: Informs drug discovery efforts by mapping residues that contribute strongly to molecular recognition.
• Protein-interface design: Supports protein-interface design by highlighting residues critical to binding energetics.
• Experimental protein engineering: Provides a computational alternative to experimental alanine-scanning for assessing residue contributions.

Methodology:

Performs computational alanine-scanning mutagenesis using BudeAlaScan to compute energetic contributions of residue-to-alanine substitutions and generates per-residue visualizations of the structural data.
