Abstract
A novel mannanase. A polypeptide having a specific amino acid sequence such as the amino acid represented by SEQ ID NO:2 exhibits a mannanase activity. Although this mannanase does not have homology with known mannanase at the amino acid level, the polypeptide has a mannanase activity as well as heat resistance.
Claims10
An expression vector comprising a polynucleotide encoding a mannanase selected from the group consisting of (a)-(h):
- (a) a polypeptide having the amino acid sequence of SEQ ID NO:
- 8;
- (b) a polypeptide having an amino acid sequence which has 90% or more identity with the amino acid sequence of SEQ ID NO:
- 8;
- (c) a polypeptide having an amino acid sequence derived from the amino acid sequence of SEQ ID NO:
- 8 by at least one of substitution, deletion and insertion of one or more and 20 or less of amino acids;
- (d) a polypeptide encoded by a base sequence which has 90% or more identity with a base sequence of SEQ ID NO:
- 7;
- (e) a polypeptide having the amino acid sequence of SEQ ID NO:
- 4;
- (f) a polypeptide having an amino acid sequence which has 90% or more identity with the amino acid sequence of SEQ ID NO:
- 4;
- (g) a polypeptide having an amino acid sequence derived from the amino acid sequence of SEQ ID NO:
- 4 by at least one of substitution, deletion and insertion of one or more and 20 or less of amino acids;
- and
- (h) a polypeptide encoded by a base sequence which has 90% or more identity with a base sequence of SEQ ID NO:
- 3.
