Thermostable polypeptide having polynucleotide kinase activity and/or phosphatase activity

摘要

Isolated polypeptides having 5'-kinase and/or 3'-phosphatase activity and temperature optimum of at least 60° C. are described. The invention also relates to isolated nucleic acids encoding the polypeptides, nucleic acid constructs and host cells comprising the nucleic acid sequences as well as methods using the polypeptides and kits for practicing the methods.
