Abstract
A DNA polymerase having an amino acid sequence comprising substantially the same amino acid sequence as that of Thermus aquaticus or Thermus flavus DNA polymerase, excluding the N-terminal 280 amino acid residues of Thermus aquaticus DNA polymerase or the N-terminal 279 amino acid residues of Thermus flavus DNA polymerase, recombinant DNA sequences encoding said DNA polymerases, vectors comprising said DNA sequences, and host cells containing such vectors. A formulation of thermostable or other DNA polymerases comprising a majority component comprised of at least one thermostable or other DNA polymerase of the type described above, wherein the DNA polymerase lacks 3'-exonuclease activity, and a minority component comprised of at least one thermostable DNA polymerase exhibiting 3'-exonuclease activity, and an improved method for enzymatic extension of DNA strands, especially while, but not limited to, amplifying nucleic acid sequences by polymerase chain reaction wherein the above formulation is made and used to catalyse primer extension, are also provided.
