Description
Nunoura et al., 2011: Here, we show the genome sequence of Candidatus ‘Caldiarchaeum subterraneum’ that represents an uncultivated crenarchaeotic group. A composite genome was reconstructed from a metagenomic library previously prepared from a microbial mat at a geothermal water stream of a sub surface gold mine. The genome was found to be clearly distinct from those of the known phyla/divisions, Crenarchaeota (hyperthermophiles), Euryarchaeota, Thaumarchaeota and Korarchaeota. The unique traits suggest that this crenarchaeotic group can be considered as a novel archaeal phylum/division. Moreover, C. subterraneum harbors an ubiquitin-like protein modifier system consisting of Ub, E1, E2 and small Zn RING finger family protein with structural motifs specific to eukaryotic system proteins, a system clearly distinct from the prokaryote-type system recently identified in Haloferax and Mycobacterium. The presence of such a eukaryote-type system is unprecedented in prokaryotes, and indicates that a prototype of the eukaryotic protein modifier system is present in the Archaea.
