All MG1655 annotations and sequence data are publicly available, and investigators can use these data in publications without contacting the genome curators. This version of the sequence was the source of GenBank record U00096.3. Ongoing annotation updates to that GenBank record are being generated from a collaboration that includes ASAP, EcoGene, the Coli Genetic Stock Center, EcoliHub, EcoCyc, RegulonDB and UniProtKB/Swiss-Prot.
