Abstract

There are provided hyperthermostable proteases having an amino acid sequences represented by SEQ ID NOs: 1, 3 and 5 of the Sequence Listing or functional equivalents thereof and hyperthermostable protease genes encoding those hyperthermostable protease. There is also disclosed a process for preparation of a hyperthermostable protease by culturing a transformant containing the gene.

Claims (6)

1. An isolated polynucleotide encoding the hyperthermostable protease comprising the amino acid sequence of SEQ ID NO:1.

2. The polynucleotide according to claim 1 , which comprises the nucleotide sequence of SEQ ID NO:2.

3. A method for preparing a hyperthermostable protease, comprising culturing a transformant transformed with the polynucleotide of claim 1 , and harvesting a hyperthermostable protease from the culture.

4. An isolated polynucleotide encoding the hyperthermostable protease comprising the amino acid sequence of SEQ ID NO:5.

5. The polynucleotide according to claim 4 , which comprises the nucleotide sequence of SEQ ID NO:6.

6. A method for preparing a hyperthermostable protease, comprising culturing a transformant transformed with polynucleotide of claim 4 , and harvesting a hyperthermostable protease gene from the culture.
