Presentation Transcript

  1. ASM Philadelphia, May 2009 How We Annotated Genomes for Free: Fast and Accurate Functional Analysis Using Subsystems Technology Rob Edwards Depts of Computer Science And Biology, San Diego State University Mathematics and Computer Sciences Division, Argonne National Laboratory http://rast.nmpdr.org/?page=Conference

  2. Pigeons If it’s good enough for Google – it’s good enough for me

  3. Annotation Servers • Complete genomes • http://rast.nmpdr.org • Metagenomes • http://metagenomics.theseed.org http://rast.nmpdr.org/?page=Conference

  4. How much has been sequenced? 100 bacterial genomes Environmental sequencing First bacterial genome 1,000 bacterial genomes Number of known sequences Year http://rast.nmpdr.org/?page=Conference

  5. How much will be sequenced? Everybody in USA Everybody at an ASM meeting One genome from every species 100 people Most major microbial environments All cultured Bacteria http://rast.nmpdr.org/?page=Conference

  6. The SEED Family http://rast.nmpdr.org/?page=Conference

  7. Subsystem Spreadsheet

  8. Over 1,000 Subsystems Three level “hierarchy” • Amino Acids and Derivatives • Alanine, serine, and glycine • Serine Biosynthesis • Amino Acids and Derivatives • Lysine, threonine, methionine, and cysteine • Methionine Biosynthesis Make your own subsystems! http://rast.nmpdr.org/?page=Conference

  9. The Annotation Process • Find the phylogenetic neighborhood of your genome • Look for proteins that related organisms have • Core proteins • Subset of all subsystems • Use those calls as a training set for critica/glimmer • Intrinsic training set! http://rast.nmpdr.org/?page=Conference

  10. This one’s for Gary

  11. Automatic Metabolic Reconstruction • Subsystem, GO, and KEGG connections • KEGG EC numbers • KEGG reaction numbers • SEED reaction numbers (Chris Henry) • Metabolic flux models • Automatically generate FBA matrices (Aaron Best/Matt DeJongh; Hope College) http://rast.nmpdr.org/?page=Conference

  12. The Populated Subsystem http://rast.nmpdr.org/?page=Conference

  13. Automatically Compare Metabolic Reconstructions

  14. Find And Suggest Candidate Functions • Rapidly correct missing annotations • Add more members to subsystems • Improves future genome annotations! (especially with new subsystems) http://rast.nmpdr.org/?page=Conference

  15. The Real Live Test • 10 genomes submitted on Thursday at 6 pm • First annotation complete before 8 am Friday • Remaining annotations completed Friday before noon • (there were others in the pipeline too!) http://rast.nmpdr.org/?page=Conference

  16. Subsystems Coverage http://rast.nmpdr.org/?page=Conference

  17. Prophages PHANTOME Mya Breitbart, Matt Sullivan, Jeff Elhai, Rob Edwards NSF Haloferax sulfurifontis prophage

  18. Metagenome Comparisons Metagenomics RAST has 300 public metagenomes Compared using tblastx http://rast.nmpdr.org/?page=Conference

  19. Human Poop

  20. High Salinity SalternsSaN Diego, July 2004 Thanks Beltran Rodriguez-Mueller, Mya Breitbart, & Forest Rohwer

  21. Low salinity salterns High salinity salterns July 2004 Nov 2005

  22. Free workshops on NMPDR, RAST, mg-RAST, SEED Contact Leslie McNeil lkmcneil@ncsa.uiuc.edu or visit http://www.nmpdr.org/ http://rast.nmpdr.org/?page=Conference
