The Methanocaldococcus jannaschii DSM 2661 genome is 1.74 Million bp long and contains approximately 1830 predicted genes. The organism's genus was formerly Methanococcus, but it has been reclassified as Methanocaldococcus. M. jannaschii is a methanogen which grows optimally at 85C, and has the distinction of being the first archaeon and first hyperthermophile sequenced.

The sequence was released August 1996 by the TIGR, and was described in Science 273:1058-73 (1996) Bult CJ, White O, Olsen GJ, Zhou L, Fleischmann RD, et al.  "Complete genome sequence of the methanogenic archaeon, Methanococcus jannaschii. "
Abstract: The complete 1.66-megabase pair genome sequence of an autotrophic archaeon, Methanococcus jannaschii, and its 58- and 16-kilobase pair extrachromosomal elements have been determined by whole-genome random sequencing. A total of 1738 predicted protein-coding genes were identified; however, only a minority of these (38 percent) could be assigned a putative cellular role with high confidence. Although the majority of genes related to energy production, cell division, and metabolism in M. jannaschii are most similar to those found in Bacteria, most of the genes involved in transcription, translation, and replication in M. jannaschii are more similar to those found in Eukaryotes....

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:

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).
