New in July 2020: We have updated MMTB and bring you new features!

  • Upload your own models and share them to the community.
  • Analyze and download published models on the fly.
  • We updated the EnzymeDetector annotations and added Eukaryotes, e.g. Homo sapiens and Arabidopsis thaliana.
  • We added KEGG pathways.
