    摘要: The invention relates to thermostable polymerases that have polymerase activity temperatures in the range from 90.degree. C. up to 113.degree. C., such as those derived from Pyrolobus fumaria, and to polynucleotides encoding the polymerases In addition, methods of designing new thermostable DNA polymerases and methods of use thereof are also provided. The polymerases have increased activity and stability at increased pH and temperature.

    摘要: A method for producing progeny polynucleotides and polypeptides by Gene Site Saturation Mutagenesis (GSSM). The method provides a set of degenerate primers corresponding to codons of a template polynucleotide, and performs polymerase elongation to produce progeny polynucleotides, which contain sequences corresponding to the degenerate primers. The progeny polynucleotides can be expressed and screened for directed evolution.
