摘要： A DNA polymerase suitable for specific isothermal amplification methods and an isothermal amplification method using the DNA polymerase are provided. In the presence of a DNA polymerase including a protein described in the following item (a) or (b), an amplification reaction of a target nucleic acid sequence in a nucleic acid sample is carried out isothermally using a first primer shown in the following (X). By using the DNA polymerase, it becomes possible to carry out the amplification reaction using the primer within a shorter time than ever before. (a) a protein having an amino acid sequence represented by SEQ ID NO. 23 (b) a protein having an amino acid sequence represented by SEQ ID NO. 25 (X) a primer that contains, in a 3′ end portion, a sequence (Ac′) that hybridizes to a sequence (A) of a 3′ end portion of the target nucleic acid sequence and also contains, on a 5′ side of the sequence (Ac′), a sequence (B′) that hybridizes to a complementary sequence (Bc) to a sequence (B) present on a 5′ side with respect to the sequence (A) in the target nucleic acid sequence

摘要： This invention provides a novel DNA polymerase obtained from Bacillus smithii JCM9076, which has novel features in terms of, for example, optimal reaction conditions (e.g., optimal temperature) and enzyme activity. More particularly, a novel DNA polymerase is a pol I type DNA polymerase, which is any of proteins (a) to (f) below and has DNA polymerase activity: (a) a protein comprising the amino acid sequence as shown in SEQ ID NO: 7; (b) a protein consisting of an amino acid sequence derived from the amino acid sequence as shown in SEQ ID NO: 7 by deletion, substitution, or addition of one or several amino acid residues; (c) a protein consisting of the amino acid sequence as shown in SEQ ID NO: 9; and (d) a protein consisting of an amino acid sequence derived from the amino acid sequence as shown in SEQ ID NO: 9 by deletion, substitution, or addition of one or several amino acid residues.
