The Haloarcula marismortui ATCC 43049 genome is 4.27 Million bp long and contains approximately 4301 predicted genes. H. marismortui is a halophilic archaeon found in the Dead Sea, where it optimally grows at around 4.5 molar salt.

The sequence was released Nov. 2004 by the Institute for Systems Biology, and was described in Genome Res 14:2221-34 (2004) Baliga NS, Bonneau R, Facciotti MT, Pan M, Glusman G, et al.  "Genome sequence of Haloarcula marismortui: a halophilic archaeon from the Dead Sea. "
Abstract: We report the complete sequence of the 4,274,642-bp genome of Haloarcula marismortui, a halophilic archaeal isolate from the Dead Sea. The genome is organized into nine circular replicons of varying G+C compositions ranging from 54% to 62%. Comparison of the genome architectures of Halobacterium sp. NRC-1 and H. marismortui suggests a common ancestor for the two organisms and a genome of significantly reduced size in the former. Both of these halophilic archaea use the same strategy of high surface negative charge of folded proteins as means to circumvent the salting-out phenomenon in a hypersaline cytoplasm. A multitiered annotation approach, including primary sequence similarities, protein family signatures, structure prediction, and a protein function association network, has assigned p...

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).
