BioCyc Credits
BioCyc is an international collaboration. This page summarizes the contributors to the BioCyc databases and website, lists data sources from which BioCyc integrates data, and lists third-party computational tools integrated within the BioCyc webiste. These credits do not cover the EcoCyc project, whose credits are listed here.

BioCyc Advisory Board
The BioCyc advisory board advises the project on a variety of matters including task prioritization, database content, user interface issues, and community outreach. The committee meets once per year.Current and former members of the advisory board are listed here.
Sources of Data Integrated into BioCyc
BioCyc incorporates information that was obtained from several sources. BioCyc publications describe the integration of data from these sources in more detail. Those sources are as follows.
- Most BioCyc genomes are obtained from the NCBI RefSeq database.
- BioCyc taxonomy information is obtained from the NCBI Taxonomy Database.
- The ExplorEnz database ---
downloaded data includes the Enzyme Nomenclature
system that classifies enzymatically catalyzed reactions.
- Gene essentiality data are obtained from the OGEE database and from individual publications.
- BioCyc 2D chemical structures are obtained from multiple sources including ChEBI and
PubChem.
- Many literature citations within BioCyc are obtained from PubMed.
- We regularly integrate Gene
Ontology annotations from UniProt into BioCyc. These data are
combined with internal Gene Ontology terms curated by BioCyc,
as follows:
- If BioCyc gene G already has GO term T, we do not add to G the annotations from UniProt to the same term (unless they differ in Evidence Code, Db-Reference, or With field)
- If UniProt contains term T1 for gene G, and BioCyc already contains term T2 for G, and T1 is an Is-A parent of T2 in the GO hierarchy, and the only annotations for T1 have evidence code IEA, and for all of these T1 annotations, there are also annotations on T2 with evidence code IEA and the same Db-Reference and With fields, then we do not add term T1 to BioCyc for G. In other words, if a less specific term T1 only has computational evidence that is duplicated by annotations to a more specific term T2, we leave away T1.
- Protein feature information from UniProt is periodically
loaded into BioCyc. UniProt protein feature data are imported into BioCyc using
the following criteria:
- If the sequence data for the UniProt protein and the BioCyc protein do not match for the region or residues of a protein feature, then the feature is not loaded.
- If a protein feature of the same type and location already exists for a BioCyc protein, then the UniProt protein feature is not imported.
- UniProt protein features related to topological domains, non-terminal residues, non-consecutive residues, and secondary structure are excluded.
- UniProt protein features of type 'Chain' which span the entire length of the protein are excluded.
-
Protein and compound 3D structures are not directly incorporated into
BioCyc, but are retrieved on-demand from the following sources, and
are subject to the copyright and terms of use of their respective sources:

- QSProteome models must be used in accordance with the terms of the originating modeling platforms (e.g., AlphaFold/ColabFold). Please credit the contributing model author when available.
- AlphaFold data retrieved from EMBL-EBI is copyright (2022) DeepMind Technologies Limited, and available for academic and commercial use under a CC BY 4.0 license, subject to the EMBL-EBI Terms of Use.
