MPA_Pathway_Tool: User-Friendly, Automatic Assignment of Microbial Community Data on Metabolic Pathways.

Area of Science:

• Microbiology
• Bioinformatics
• Systems Biology

Background:

• Microbial communities in environments like the human gut and biogas plants are increasingly studied using multi-omics methods.
• Understanding microbial function relies on assigning genes, transcripts, or proteins to biological pathways.
• Standard pathway maps often struggle with the complexity and novelty of microbial metabolism.

Purpose of the Study:

• To implement and validate a user-friendly web application for microbial pathway analysis.
• To address the challenges of mapping microbial community data to biological pathways.
• To facilitate the taxonomic and functional characterization of microbial communities.

Main Methods:

• Development of a stand-alone web application named MPA_Pathway_Tool.
• The tool comprises two modules: 'Pathway-Creator' for user-defined pathways with taxonomic constraints and 'Pathway-Calculator' for data mapping and visualization.
• Implementation using Java and ReactJS.

Main Results:

• Successful implementation and validation of the MPA_Pathway_Tool.
• The tool enables easy setup of custom pathways and automatic mapping of microbial community data.
• Visualization of results aids in understanding community functions and metabolic capabilities.

Conclusions:

• The MPA_Pathway_Tool offers a practical solution for analyzing microbial community functions across diverse environments.
• It simplifies the process of linking multi-omics data to biological pathways, overcoming limitations of standard maps.
• This tool supports researchers in gaining deeper insights into microbial metabolism and community dynamics.
