Area of Science:

  • Glycomics
  • Mass Spectrometry (MS)
  • Structural Biology

Background:

  • Mass spectrometry (MS) is crucial for oligosaccharide structural analysis due to its accuracy, sensitivity, and speed.
  • High-throughput glycan mass spectra interpretation remains a bottleneck in glycomics due to limited automation and reliance on specialized expertise.
  • Current software requires manual preprocessing of MS data, including the identification of monoisotopic peaks.

Purpose of the Study:

  • To develop an automated platform for mass spectrometry (MS) data evaluation in glycomics with minimal human intervention.
  • To streamline the interpretation of complex glycan mass spectra for high-throughput analysis.
  • To facilitate the rapid assignment of known and novel oligosaccharide structures.

Main Methods:

  • Development of the SysBioWare platform for MS data evaluation.
  • Import of raw MS data into a spectrum browser.
  • Application of de-noising and wavelet analysis for peak processing.
  • Isotopic grouping and monoisotopic m/z value determination.
  • Compositional assignment using a tuned building block library.

Main Results:

  • SysBioWare enables low human intervention in MS data evaluation for glycomics.
  • The platform successfully performs isotopic grouping and compositional assignment of glycan structures.
  • Automated processing significantly speeds up the analysis of mass spectra.
  • The platform was applied to human urine glycome for rapid structure identification.

Conclusions:

  • SysBioWare provides a potent tool for the rapid assignment of known and novel oligosaccharide structures in glycomics.
  • The developed platform addresses the need for automated and efficient MS data interpretation in high-throughput glycomics projects.
  • This advancement facilitates broader application of MS in glycomics research by reducing reliance on specialized knowledge.
