The invention provides novel nucleic acid polymerases from strains GK24 and RQ-1 of Thermus thermophilus , and nucleic acids encoding those polymerases, as well as methods for using the polymerases and nucleic acids.
1. A method of synthesizing DNA comprising contacting an isolated polypeptide comprising SEQ ID NO: 14 with a DNA under conditions sufficient to permit polymerization of DNA.
2. A method of primer extension comprising contacting an isolated polypeptide comprising SEQ ID NO: 14 with a primer and a nucleic acid that is complementary to the primer under conditions sufficient to permit polymerization of DNA.
3. The method of claim 2 wherein the nucleic acid is DNA.
4. The method of claim 2 wherein the primer extension is done to sequence the nucleic acid.
5. The method of claim 2 wherein the primer extension is done to amplify the nucleic acid.
