Basic Help for BioCyc

How to Search BioCyc

The first step in querying BioCyc is to select the database you wish to query. You can select a database in two places:

  • Click on the words change organism database under the "Quick Search" box in the upper right corner
  • Click on the words change organism database at the bottom of the toolbar Search menu or Tools menu

The BioCyc Web site provides a variety of search tools to help you find the information you are looking for.

  • Search by words and database fields: All BioCyc databases, such as EcoCyc, provide three layers of searches.

    • Quick Search: Enter one or more words or text fragments in the box to the upper right of the toolbar and click Search. [more details]

    • Search by single object type from Toolbar Search menu [more details].
      These searches allow filtering on multiple attributes of a single type of object. Examples:
      • Search Menu → Genes/Proteins/RNAs
      • Search Menu → Pathways

    • Advanced searches: Search Menu → Advanced [more details]
      These searches allow very sophisticated filtering on attributes and relationships of multiple object types.

  • Search by ontology: See Search Menu → Ontologies [more details]

  • BLAST search: See Search Menu → BLAST [more details]

  • Search BioCyc Web pages: See Search Menu → Google this Site [more details]

  • Search the full text of the E. coli literature: See Search Menu → Search Full-text Articles [more details]

BioCyc Tools

Please explore the Genome, Metabolism, and Analysis menus, which offer a variety of software tools including visualization of genome maps, metabolic networks, and regulatory networks; multiple tools for analysis of omics data; and comparative analyses and reports.

Right Operations Menu

At the right side of pages such as gene, metabolite, and pathway pages, is the right-operations menu. The menu offers commands for operating on the currently displayed object, e.g., for showing the current gene within a comparative genome browser, or for customizing the appearance of the current pathway. The contents of this menu change depending on the type of object currently displayed.
