The Thermoplasma volcanium GSS1 genome is 1.58 Million bp long and contains approximately 1548 predicted genes. T. volcanium is a thermophilic, acidophilic mycoplasma that grows optimally at 60C and pH 2.0. This species is a facultative aerobe. The thermoplasamas are euryarchaea, distantly related to sulfolobes which are crenarchaea, yet both inhabit similar thermal acidic environments.

The sequence was released Dec 2004 by the National Institute of Advanced Industrial Science and Technology, Japan, and was described in Proc Natl Acad Sci U S A 97:14257-62 (2000) Kawashima T, Amano N, Koike H, Makino S, Higuchi S, et al.  "Archaeal adaptation to higher temperatures revealed by genomic sequence of Thermoplasma volcanium. "
Abstract: The complete genomic sequence of the archaeon Thermoplasma volcanium, possessing optimum growth temperature (OGT) of 60 degrees C, is reported. By systematically comparing this genomic sequence with the other known genomic sequences of archaea, all possessing higher OGT, a number of strong correlations have been identified between characteristics of genomic organization and the OGT. With increasing OGT, in the genomic DNA, frequency of clustering purines and pyrimidines into separate dinucleotides rises (e.g., by often forming AA and TT, whereas avoiding TA and AT). Proteins coded in a genome are divided into two distinct subpopulations possessing isoelectric points in different ranges (i.e., acidic and basic), and with increasing OGT the size of the basic subpopulation becomes larger.

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).
