PGfinder

PGfinder automates structural analysis of bacterial peptidoglycans to quantify peptidoglycan (PG) fragments and identify novel structural features for peptidoglycomics studies.

Key Features:

• Specialized peptidoglycan analysis: Focuses on structural analysis of peptidoglycan rather than general proteomics or glycomics approaches.
• Quantification of PG fragments: Provides quantitative analysis of peptidoglycan (PG) fragments.
• Discovery of novel structural features: Identifies previously unreported structural elements within peptidoglycan molecules.
• Glycan and peptide-stem analysis: Analyzes glycan chains and peptide stems containing unusual amino acids and sugars.
• Automated workflow: Implements automation to replace manual analysis steps.
• Use of open-access resources: Leverages open-access resources to construct the analysis workflow.
• Standardization and reproducibility: Produces standardized and reproducible outputs for comparative studies.
• High-resolution and high-throughput support: Targets high-resolution structural analysis and enables high-throughput peptidoglycomics workflows.

Scientific Applications:

• Quantitative peptidoglycan profiling: Enables quantitative comparison of PG fragment abundances across samples.
• Structural discovery in peptidoglycomics: Facilitates identification and characterization of novel peptidoglycan structures.
• Standardized comparative studies: Supports reproducible, standardized analyses for peptidoglycomics research.
• High-throughput structural surveys: Enables large-scale, high-resolution surveys of bacterial peptidoglycan composition.

Methodology:

Automates computational analysis using a workflow that leverages open-access resources to analyze glycan chains and peptide stems, quantify PG fragments, and identify structural features.
