Thermostable type-A DNA polymerase mutants with increased polymerization rate and resistance to inhibitors

The present invention provides mutants of DNA polymerases having an increased rate of incorporation of nucleotides into nucleic acids undergoing polymerization and having an enhanced resistance to inhibitors of DNA polymerase activity. The mutant polymerases are well suited for fast PCR applications...

More Information
Summary:The present invention provides mutants of DNA polymerases having an increased rate of incorporation of nucleotides into nucleic acids undergoing polymerization and having an enhanced resistance to inhibitors of DNA polymerase activity. The mutant polymerases are well suited for fast PCR applications, for PCR amplification of targets in samples that contain inhibitors of wild-type polymerases, and for fast PCR amplification of samples containing DNA polymerase inhibitors. In exemplary embodiments, the mutants are mutants of Taq DNA polymerase.
