Archaea Genomes - PYROCOCCUS HORIKOSHII

Pyrococcus horikoshii is a hyper-thermophilic archaebacterium. As an extremophile it grows optimally at 98 degrees C, pH 7.0 and NaCl concentration 2.4%. Sequence comparison among the assigned ORFs of P. horikoshii suggested that a considerable number of ORFs were generated by sequence duplication. All the assigned ORFs and RNA coding regions occupied 91.25% of the whole genome.

P. horikoshii was isolated near a hydrothermal vent at the Okinawa Trough.

Genome analyses of Pyrococcus horikoshii OT3 and other hyperthermophiles have made an important contribution to the knowledge of the structures of substances such as proteins and enzymes to show which are suitable for use in an extreme environment.
