Presentation Transcript

  1. AraCyc Metabolic Pathway Annotation

  2. AraCyc – An overview • AraCyc is a metabolic pathway database for Arabidopsis thaliana; • Computational prediction by PathoLogic software using MetaCyc as the reference database (Peter Karp, SRI); • Predicted pathways were then manually validated; ongoing manual curation.

  3. Recent AraCyc releases

  4. Upcoming AraCyc 4.0 • New pathways, updated pathways • Gene function annotation updated according to TAIR7 genome release • Significant changes of the assignment of genes to reactions/pathways

  5. Outline • Search and browse AraCyc • Arabidopsis Metabolic map • OmicsViewer

  6. Search AraCyc Browse pathways, enzymes, genes, compounds OMICS Viewer Paint data from high-throughput experiments on the metabolic map AraCyc Tutorials Metabolic Map ‘Bird’s eye’ view of the Arabidopsis metabolic network Data submission

  7. A pathway example: sucrose biosynthesis

  8. A pathway example: sucrose biosynthesis Beta-D-glucose-6-phosphate Enzyme: phosphoglucomutase Evidence: Inferred by a human based on computational evidence [Kofler00], Inferred from direct assay [Periappura00] Gene: PGM Alpha-D-glucose-1-phosphate = alpha-D-glucose-6-phosphate
