Species InformationThe Pyrococcus horikoshii OT3 genome is 1.74 Million bp long and contains approximately 2005 predicted genes. P. horikoshii is a hyperthermophilic archaeon isolated from a hydrothermal vent at a depth of 1395 meters in the Okinawa Trough in the Pacific Ocean. It grows optimally at 98C.
Taxonomy: Archaea; Euryarchaeota; Thermococci; Thermococcales; Thermococcaceae; Pyrococcus.
Sequencing: The sequence was released April 1998 by the NITE, and was described in DNA Res 5:55-76 (1998) Kawarabayasi Y, Sawada M, Horikawa H, Haikawa Y, Hino Y, et al.."Complete sequence and gene organization of the genome of a hyper-thermophilic archaebacterium, Pyrococcus horikoshii OT3." Abstract: The complete sequence of the genome of a hyper-thermophilic archaebacterium, Pyrococcus horikoshii OT3, has been determined by assembling the sequences of the physical map-based contigs of fosmid clones and of long polymerase chain reaction (PCR) products which were used for gap-filling. The entire length of the genome was 1,738,505 bp. The authenticity of the entire genome sequence was supported by restriction analysis of long PCR products, which were directly amplified from the...

"Pyrococcus horikoshii sp. nov., a hyperthermophilic archaeon isolated from a hydrothermal vent at the Okinawa Trough." Abstract: A hyperthermophilic, anaerobic archaeon was isolated from hydrothermal fluid samples obtained at the Okinawa Trough vents in the NE Pacific Ocean, at a depth of 1395m. The strain is obligately heterotrophic, and utilizes complex proteinaceous media (peptone, tryptone, or yeast extract), or a 21-amino-acid mixture supplemented with vitamins, as growth substrates. Sulfur greatly enhances growth. The cells are irregular cocci with a tuft of flagella, growing optimally at 98 degrees C...
