Pathway Tools is a comprehensive software environment that supports construction of organism-specific databases
+
called Pathway/Genome Databases (PGDBs). A PGDB such as [http://ecocyc.org/ EcoCyc]
+
is a bioinformatics DB that integrates genomic data with detailed functional annotations
+
of the genome, such as descriptions of metabolic and signaling pathways. A PGDB is a
+
type of model-organism DB.
+
 
+
Pathway Tools functionality includes:
+
 
+
* Prediction, editing, querying, and visualization of metabolic pathways, reactions, and metabolites.
+
* Generation of steady-state metabolic flux models from PGDBs using flux-balance analysis.
+
* Generation of metabolic-map diagram and of metabolic map poster ([http://bioinformatics.ai.sri.com/posters/ecoli-metab.pdf example]).
+
* Editing and visualization of signaling pathways.
+
* Editing, querying, and visualization of regulatory interactions and regulatory networks.
+
* Genome browser; comparative genome browser; generation of genome poster ([http://bioinformatics.ai.sri.com/posters/ecoli-genome.pdf example]).
+
 
+
Flux-balance analysis models generated by Pathway Tools can make a variety
+
of phenotypic predictions, such as predicting the phenotype of knock-out mutants.
+
 
+
Pathway Tools supports analysis of omics datasets (e.g., gene expression and
+
metabolomics) by painting omics data onto a diagram
+
of the full metabolic map of the organism, or onto a diagram of the full
+
regulatory network.  Pathway Tools also computes several variations of
+
enrichment analysis.
+
 
+
Pathway Tools performs metabolic network analyses including finding
+
choke points (potential drug targets) in metabolic networks, dead-end metabolite
+
analysis, and reachability analysis.
+
 
+
Pathway Tools has its own genome browser, which has a microbial orientation.  In addition,
+
Pathway Tools
+
can be coupled with other genome browsers to add support for pathways to an existing MOD,
+
such as was done for SGD and DictyBase.
+
 
+
Pathway Tools was developed by [http://www.ai.sri.com/pkarp/ Peter D. Karp] and coworkers at the [http://bioinformatics.ai.sri.com/ Bioinformatics Research Group] at SRI International.

About Pathway Tools

Pathway Tools is a comprehensive symbolic systems biology software system that supports several use cases in bioinformatics and systems biology:

  • Development of organism-specific databases called Pathway/Genome Databases (PGDBs) that integrate many bioinformatics datatypes, from genomes to pathways to regulatory networks.
  • Development of metabolic-flux models using flux-balance analysis
  • Scientific visualization, web publishing, and dissemination of those organism-specific databases, including:
    • Automatic display of metabolic pathways and full metabolic networks; generation of metabolic map diagram and of metabolic map poster (example).
    • Genome browser; comparative genome browser; generation of genome poster (example).
    • Display of operons, regulons, and full transcriptional regulatory networks
  • Analysis of omics datasets, including painting omics data on to diagrams of the full metabolic network, enrichment analysis.
  • Computational inferences including prediction of metabolic pathways, prediction of metabolic pathway hole fillers, prediction of operons
  • Comparative analyses of model-organism databases.
  • Analysis of biological networks:
    • Interactively tracing metabolites through the metabolic network
    • Finding dead-end metabolites in metabolic networks
    • Identifying choke points (potential drug targets) in metabolic networks

Pathway Tools has four components:

  • PathoLogic: Creates a new PGDB containing the predicted metabolic pathways of an organism, given a Genbank entry as input.
  • Pathway/Genome Navigator: Supports query, visualization, and analysis of PGDBs. The Navigator powers the BioCyc web site at BioCyc.org.
  • MetaFlux: Supports development of metabolic flux models from Pathway/Genome Databases.
  • Pathway/Genome Editors: Provide interactive editing capabilities for PGDBs.
