List of BioCyc Pathway/Genome Databases

The 20,050 databases within the BioCyc collection as of December 8, 2023 (version 27.5) are as follows.

The EcoCyc database is freely available to all users because its curation is supported by NIH funding. Also free is the database for the cyanobacterium Arthrospira platensis NIES-39 as an example of a Tier 3 database. The other BioCyc databases are available via subscription, which supports their curation.

Tier 1 Databases

PGDBs in Tier 1 have received at least one year of literature-based curation by scientists. For example, the EcoCyc DB is the result of more than 20 person-years of effort to enter information from the E. coli literature about the metabolism, transport, and genetic regulatory processes of this organism, and to update the genome annotation to reflect newly characterized E. coli genes.

Tier 2 Databases

PGDBs in Tier 2 were generated by the PathoLogic program, which was used to predict their metabolic pathways, their operons (for bacteria only), and their pathway hole fillers (for many of the PGDBs). The resulting PGDBs underwent manual review and curation to remove false-positive pathway predictions, add new protein functions and metabolic pathways from the literature, create protein complexes, and connect enzymes with reactions they catalyze. In some cases external datasets (e.g., gene essentiality data) have been loaded into these PGDBs. Most Tier 2 PGDBs have undergone 1-4 months of curation.

Tier 3 Databases

The 19,936 PGDBs in Tier 3 were generated by the PathoLogic program, which was used to predict their metabolic pathways and their operons (for bacteria only). The resulting PGDBs did not undergo manual review of the pathway predictions, nor subsequent literature curation. Therefore, the pathway predictions should be treated with due caution. PathoLogic is tuned to err on the side of over-predicting pathways to bring them to scientists' attention, rather than under-predicting pathways.

The Tier 3 DBs are available for adoption [more] by interested scientists, to undergo curation and updating.
