About the Escherichia coli K12 - (eschColi_K12) assembly (sequences)
 

Species Information

The Escherichia coli K12 substr. MG1655 genome is 4.64 Million bp long and contains approximately 4466 predicted genes.

Taxonomy: Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacteriales; Enterobacteriaceae; Escherichia.

Sequencing: The sequence was released - and was described in Nucleic Acids Res 34:1-9 (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 annotation is complete at any moment in time. This is a snapshot analysis based on the most recent genome sequences of two E.coli K-12 bacteria. An accurate and up-to-date description of E.coli K-12 genes is of particular importance to the scientific community because experimentally determined properties of its ge...

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