Escherichia coli K12, complete genome

NCBI Genomes web site provides computational tools for better visualization of the genome sequence and the properties of predicted proteins. Feature tables list the DNA coordinates of the structural RNA- and protein-coding genes, their names, and the direction of transcription and allow retrieval of the corresponding DNA fragments. In addition, the Protein feature table lists UWisconsin b-numbers (where available), predicted protein functions and the corresponding protein family entries in the COG database. TaxMap shows the distribution of the genes with closest homologs among Bacteria, Archaea, or Eukaryotes and allows easy visualization of regions, most likely derived by interkingdom gene transfer. TaxPlot allows a three-way comparison of E. coli genes with genes from any other sequenced genomes, which is useful for comparing relative proximity of E. coli to other bacterial genomes and for identifying genes that have particularly close homologs in genomes of other species. This approach often allows identification of recently acquired foreign genes that can be involved in pathogenicity.
