Contains information on networks of metabolic and regulatory and interactions in Arabidopsis. This information is based on input from biologists in their area of expertise. In addition to the MetNet-curated interactions, Aracyc-curated pathways and AGRIS-curated regulatory network are provided. The data in MetNetDB is updated regularly. Types of interactions in MetNetDB include transcription, translation, protein modification, assembly, allosteric regulation, translocation from one subcellular compartment to another.
