The Vibrio cholerae O1 biovar eltor str. N16961 genome is 4.03 Million bp long and contains approximately 4008 predicted genes.

The sequence was released 08/22/2000 by the TIGR, and was described in Nature 406:477-83 (2000) Heidelberg JF, Eisen JA, Nelson WC, Clayton RA, Gwinn ML, et al.  "DNA sequence of both chromosomes of the cholera pathogen Vibrio cholerae. "
Abstract: Here we determine the complete genomic sequence of the gram negative, gamma-Proteobacterium Vibrio cholerae El Tor N16961 to be 4,033,460 base pairs (bp). The genome consists of two circular chromosomes of 2,961,146 bp and 1,072,314 bp that together encode 3,885 open reading frames. The vast majority of recognizable genes for essential cell functions (such as DNA replication, transcription, translation and cell-wall biosynthesis) and pathogenicity (for example, toxins, surface antigens and adhesins) are located on the large chromosome. In contrast, the small chromosome contains a larger fraction (59%) of hypothetical genes compared with the large chromosome (42%), and also contains many more genes that appear to have origins other than the gamma-Proteobacteria. The small chromosome also ca... [Click above reference link for full abstract]

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 @soe.ucsc.edu).
