In accordance with the present invention, there is provided a thermostable enzyme obtainable from Pyrococcus sp . which catalyzes the polymerization of DNA. The thermostable enzyme obtainable from Pyrococcus sp ., an archaebacterium isolated from a submarine thermal vent at 2010 meters, is a DNA polymerase which has an apparent molecular weight of about 92,000-97,000 daltons, a half-life of about 8 hours at 100°C and a half-life of 23 hours at 95°C. |
