DNA FRAGMENT HAVING HEAT-RESISTANT DNA POLYMERASE GENE INFORMATION AND ITS USE

摘要

PURPOSE:To provide a production process for a heat-resistant DNA polymerase of high productivity by collecting a heat-resistant DNA polymerase gene, analyzing the primary structure and applying the genetic engineering technique. CONSTITUTION:A process for producing heat-resistant DNA polymerase characterized by collecting a heat-resistant DNA polymerase originating from Thermus thermophilus, or a DNA encoding a substance functionally equal to the heat- resistant DNA polymerase, a recombinant vector containing the DNA or culturing a transformer prepared by transforming host cells with the recombinant vector to collect the heat-resistant DNA polymerase.
