Abstract
The present invention relates to a thermostable Flap endonuclease whose optimum temperature is 75° C. or more and DNA coding for (a) a protein consisting of the amino acid sequence shown in SEQ ID NO:2 or (b) a protein with Flap endonuclease activity, consisting of an amino acid sequence where in the amino acid sequence (a), one or more amino acids are deleted, substituted or added. According to the present invention, there is provided a thermostable Flap endonuclease whose optimum temperature for reaction is 75° C. or more. Further, this enzyme is thermally stable, so it becomes possible to develop new techniques of conducting artificial homologous recombination or genetic shuffling highly efficiently by coupling the enzyme reaction with PCR.
