SEAS is a new computational tool for pathway enrichment analysis of omic data in bacteria. It accurately maps genes to biological pathways in the SEED database, identifying more organism-specific pathways than existing tools.

Area of Science:

Bioinformatics
Computational Biology
Systems Biology

Background:

Pathway enrichment analysis is crucial for interpreting high-throughput omic data.
It connects differentially expressed genes/proteins to known biological pathways.
Analyzing bacterial pathways requires specialized tools and databases.

Purpose of the Study:

To introduce SEAS, a novel computational tool for pathway enrichment analysis.
To enable analysis of gene sets from specific organisms against the SEED database.
To improve the identification of organism-specific bacterial pathways.

Main Methods:

SEAS utilizes gene ID and orthology mapping to link input gene sets to SEED pathway genes.
Statistical significance is calculated for the enrichment of each SEED pathway by the mapped genes.
