Thermostable nucleic acid polymerase from Thermococcus gorgonarius

摘要

A purified thermostable enzyme is derived form the thermophilic archaebacterium Thermococcus gorgonarius. The enzyme can be native or recombinant, retains approximately 90 % of its activity after incubation for two hours at 95 DEG C in the presence of stabilizing agents and possesses 3'-5' proofreading exonuclease activity. Thermostable DNA polymerases are useful in many recombinant DNA techniques, especially nucleic acid amplification by the polymerase chain reaction (PCR).
