DNA encoding thermostable nucleic acid polymerase enzyme from thermus species Z05

摘要

A purified thermostable enzyme is derived from the eubacterium Thermus species Z05. The enzyme has DNA polymerase, activity reverse transcriptase activity, and optionally 5'->3' exonuclease activity. The enzyme can be native or recombinant, and may be used with primers and nucleoside triphosphates in a temperature-cycling chain reaction where at least one nucleic acid sequence is amplified in quantity from an existing sequence.
