GPMAW

GPMAW provides analysis of proteins and peptides for mass spectrometric interpretation by performing sequence acquisition, in silico proteolytic digestion, theoretical peptide fragmentation prediction, sequence annotation, and secondary structure prediction.

Key Features:

• Integrated protein sequence acquisition: Retrieves and imports protein sequences for downstream computational analyses.
• Proteolytic digest simulation: Simulates enzymatic proteolytic digests to predict resulting peptide fragments.
• Theoretical peptide fragmentation analysis: Predicts peptide fragmentation patterns and masses expected in mass spectrometry.
• Detailed annotation: Annotates protein and peptide sequences with features and post‑translational modifications.
• Secondary structure prediction: Predicts protein secondary structure elements from primary sequence.

Scientific Applications:

• Mass spectrometric data interpretation: Assists interpretation of experimental mass spectrometry data by providing simulated digestion and fragmentation outputs.
• Protein characterization: Supports sequence annotation and identification of modifications for protein characterization workflows.
• Structural biology: Supplies secondary structure predictions to inform structural biology analyses.

Methodology:

Computational steps explicitly include integrated sequence acquisition, in silico proteolytic digest simulation, theoretical peptide fragmentation prediction, sequence annotation, and secondary structure prediction.
