1. A method for detecting a target nucleic acid comprising:
exposing a composition comprising a purified thermostable FEN-1 endonuclease from an archaebacterial species selected from the group consisting of Pyrococcus furiosus and Methanococcus jannaschii and a purified nucleic acid molecule, wherein said purified nucleic acid molecule is capable of hybridizing to a target nucleic acid to form a FEN-1 endonuclease cleavage structure, to a sample suspected of containing said target nucleic acid;
forming a FEN-1 endonuclease cleavage structure; and
cleaving said FEN-1 endonuclease cleavage structure with said purified thermostable FEN-1 endonuclease, such that said target nucleic acid is detected.
