16. Stakeholders' Requirements • Data source to be acknowledged • Free and open access to the data • Scope: Enzyme related resources

17. User Requirements - Functionalities • Search • Free text • Protein sequence • Chemical structure • Browse • EC classification • Expression • Taxonomy • Disease • Chemical compound • Compare enzymes • Customized downloads

18. User Requirements - Content • Enzyme Headline • Pathway • Reaction • Structure-Function • Diseases and Drugs • References

19. Searching • The initial query is resolved into UniProt accessions: • Keyword search: • Uses EBI search web service • Protein sequence search: • Uses NCBI-BLAST web service • UniProt accessions are filtered for enzymes and grouped as orthologs. • A summary is built for every ortholog group using UniProt and IntEnz web services. • Search results include ‘tags’ for related species, chemical compounds and diseases, which allow their filtering.

20. Enzyme data Retrieved on demand from the source: • Enzyme highlight IntEnz and UniProt WS • Structure PDBe WS (DAS) • Reactions and pathways  Rhea and Reactome WS • Small molecules  UniProt, ChEMBL, IntEnz, ChEBI WS • Disease  UniProt and BioPortal WS (EFO, OMIM, MeSH) • Literature Europe PubMed Central , UniProt and PDBe WS

21. No releases, no curation • Data is retrieved fresh from the source on demand. • Only a minimal map of cross-references is kept in a database in order to speed up the building of search filters. The map is rebuilt immediately after every UniProt release.
