| Summary | EcoCyc is a model-organism database for Escherichia coli K-12 MG1655, the strain from which the first complete genome sequence was obtained for E. coli [Blattner97]. The source of the original K-12 isolate came from a stool sample from a patient with diptheria in 1922, but the name, K-12, is more difficult to pin down (see Microbiology Today, Escherichia coli and Small Things Considered, How did E. coli get named K-12?). The genome sequences used in EcoCyc have been updated from the original Blattner et al. sequence through a collaboration between EcoCyc, the University of Wisconsin, UniProtKB/Swiss-Prot, and the National Center for Biotechnology Information (NCBI). The E. coli genome sequence used in EcoCyc currently was updated from version 2 to version 3, GenBank accession number U00096.3, at release 20.0 of EcoCyc. Annotation updates to the NCBI U00096.3 from EcoCyc are ongoing. However, despite the involvement of EcoCyc staff in these ongoing updates to the U00096 record, some annotation differences may be found, such as due to recent updates to EcoCyc. EcoCyc also collaborates with the Gene Ontology Consortium and UniProtKB to maintain consistency between the databases.
