19 SRI International Bioinformatics Why Create PGDBs? Extract more information from your genome Create an up-to-date computable information repository about an organism Perform analyses on the genome and pathway complement of the organism l Analyses of omics data l Analyses of cellular systems (dead-end metabolites) l Reports generated by Pathway Tools Perform comparative analyses with other organisms Generate a genome poster and metabolic wall chart

31 SRI International Bioinformatics Comparison of BioCyc to KEGG: The Data KEGG approach: Static collection of pathway diagrams that are color-coded to produce organism-specific views KEGG vs MetaCyc: Resource on literature-derived pathways l KEGG pathway maps are composites of pathways in many organisms -- do not identify what specific pathways elucidated in what organisms l KEGG pathway maps encompass multiple biological pathways; are 2-4 times the size of MetaCyc pathways l KEGG has no literature citations, no summaries, less enzyme detail KEGG vs BioCyc organism-specific PGDBs l KEGG re-annotates entire genome for each organism l KEGG does not curate or customize pathway networks for each organism

32 SRI International Bioinformatics Comparison of Pathway Tools to KEGG: The Software KEGG has no pathway hole filler or transport inference parser or operon predictor KEGG has no interactive editing tools – you cannot refine a KEGG pathway DB KEGG has no algorithmic visualization tools – pathway diagrams are pre-drawn l May become out of date l Cannot show pathways at multiple detail levels KEGG genome browser has very limited functionality KEGG has one overview diagram with limited functionality KEGG has no metabolite tracing tool KEGG has no Structured Advanced Query Tool

33 SRI International Bioinformatics Overviews and Omics Viewers Genome-scale Visualizations l Metabolic map l Transcriptional regulatory network l Genome map Overlay gene expression, proteomics, metabolomics data Obtain pathway based visualizations of omics data l Numerical spectrum of expression values mapped to a color spectrum l Steps of overview painted with color corresponding to expression level(s) of genes that encode enzyme(s) for that step

34 SRI International Bioinformatics Environment for Computational Exploration of Genomes Powerful ontology opens many facets of the biology to computational exploration Global characterization of metabolic network Analysis of interface between transport and metabolism Nutrient analysis of metabolic network

35 SRI International Bioinformatics Pathway Tools Implementation Details Allegro Common Lisp Sun, Linux, Windows, Macintosh platforms Ocelot object database 370,000+ lines of code Lisp-based WWW server at l Manages 370+ PGDBs

36 SRI International Bioinformatics The Common Lisp Programming Environment Gatt studied Lisp and Java implementation of 16 programs by 14 programmers (Intelligence 11:21 2000)

37 SRI International Bioinformatics Peter Norvigs Solution I wrote my version in Lisp. It took me about 2 hours (compared to a range of 2-8.5 hours for the other Lisp programmers in the study, 3-25 for C/C++ and 4-63 for Java) and I ended up with 45 non-comment non-blank lines (compared with a range of 51-182 for Lisp, and 107-614 for the other languages). (That means that some Java programmer was spending 13 lines and 84 minutes to provide the functionality of each line of my Lisp program.)

38 SRI International Bioinformatics Survey Please complete survey at end of each day

39 SRI International Bioinformatics PGDB(s) That You Build Before you leave l Tar up your PGDB directory and FTP it home, email it home, or copy it to flash disk l We will create a backup copy of your PGDB directory if the directory is still there at the end of the tutorial l Delete the PGDB directory if you dont want us to back it up l We will not give the backed up data to anyone else
