11 May 2010



There is provided an extremely thermostable enzyme obtainable from Thermococcus litoralis. The thermostable enzyme has a molecular weight of about 90,000-95,000 daltons, a half-life of about 60 minutes at 100 DEG C. in the absence of stabilizer, and a half-life of about 95 minutes at 100 DEG C. in the presence of stabilizer, such as octoxynol (TRITON X-100) or bovine serum albumin. The thermostable enzyme possesses a 3'-5' proofreading exonuclease activity. The thermostable enzyme may be native or recombinant and may be used for second-strand cDNA synthesis in cDNA cloning, DNA sequencing, and DNA amplification.
