Pyrococcus Furiosus
Pyrococcus furiosus is an hyperthermophilic organism found in submarine vents, its DNA polymerase is thus stable at very high temperatures (thermostable). Pfu DNA polymerase is an archeal DNA polymerase so it is classed as a Family B polymerase. Pfu polymerase is especially useful as it has a 3' to 5' proofreading exonuclease ability for excision of an incorrect DNA base pair after which the polymerase re-inserts the correct base pair.
