SPACEPro

SPACEPro evaluates protein cleavage efficiency from data-dependent acquisition mass spectrometry to provide quantitative metrics for enzymatic and chemical cleavage in shotgun proteomics.

Key Features:

• Multi-Level Analysis: Evaluates cleavage efficiency at peptide-spectrum match (PSM), peptide, and protein levels.
• Data-Dependent Mass Spectrometry Integration: Operates on data-dependent acquisition (DDA) mass spectrometry datasets.
• Efficiency and Reproducibility Metrics: Computes metrics that quantify cleavage efficiency and reproducibility of peptide generation.
• Output Formats: Exports results as human-readable text files and JSON files.
• Protocol Development Support: Provides metrics and insights to assess and refine enzymatic and chemical sample preparation protocols.

Scientific Applications:

• Cleavage Method Assessment: Comparing and assessing effectiveness of enzymatic and chemical cleavage methods.
• Quantitative Proteomics Quality Control: Ensuring reproducibility and reliability of peptide generation for downstream quantitative proteomics.
• Sample Preparation Optimization: Guiding optimization of sample preparation protocols in shotgun proteomics workflows.

Methodology:

Analyzes mass spectrometry data acquired by data-dependent acquisition and systematically evaluates cleavage efficiency at the peptide-spectrum match (PSM), peptide, and protein levels.
