The Escherichia coli K12 genome is 4.64 Million bp long and contains approximately 4435
predicted genes.
The sequence was released 09/05/1997 by the University of Wisconsin-Madison, USA, and was described
in Nucleic Acids Res :1-9 (2006) Riley M, Abe T, Arnaud MB, Berlyn MK, Blattner FR, et al. "Escherichia coli K-12: a cooperatively developed annotation snapshot--2005.

Abstract: The goal of this group project has been to coordinate and bring up-to-date information on all genes of Escherichia coli K-12. Annotation of the genome of an organism entails identification of genes, the boundaries of genes in terms of precise start and end sites, and description of the gene products. Known and predicted functions were assigned to each gene product on the basis of experimental evidence or sequence analysis. Since both kinds of evidence are constantly expanding, no...

Sample position queries
A genome position can be specified by chromosomal coordinate range, COG
ID, or keywords from the GenBank or TIGR description of a gene.
The available chromosome/plasmid names are:
| Browser Chrom/Plasmid Name | Length (bp) | GC Content (%) | Gene Count | NCBI RefSeq Accession |
|---|
| chr | 4639675 | 50.79 | 4435 | NC_000913 |
The following list shows examples of valid position queries for this
genome:
| Request: | Genome Browser Response: |
|---|
| chr | Displays the entire sequence "chr" in the browser window |
| chr:1-10000 | Displays first ten thousand bases of the sequence "chr" |
| transporter | Lists all genes with "transporter" in the name or description |
| b0010 | Display genome at position of gene b0010 |

The Archaeal Genome Browsers at UCSC were developed by members of the
Lowe Lab (Kevin Schneider,
Katherine Pollard, Andy Pohl, Todd Lowe) and Robert Baertsch, with significant support from
the UCSC Human Genome
Browser group.
The Archaeal Browsers are run by a slightly modified
version of the UCSC Human Genome
Browser system. All queries, bug reports, content corrections, suggested improvements,
and new track data submissions should be sent to Todd Lowe (lowe
