Claims16
A method for producing an alkaline phosphatase (ALP), comprising a step of culturing an Aspergillus transformant capable of producing the ALP.
A glycosylated alkaline phosphatase (ALP) II having a molecular weight of 80 to 150 kDa as measured by a gel filtration method.
A vector for Aspergillus transformation, comprising a nucleotide sequence encoding an amino acid sequence of an ALP having an Aspergillus strain-derived secretory signal peptide selected from the group consisting of CDHss, CDHcytbkex, CDHcytbKexmut1, CDHcytbKexmut2, CDHcytbKexmut3, CDHcytbKexmut4, CDHall, GlaBss, CelBss, CelB, SKIK_CDHss, AsAP1ss54, and AsAP3ss72 on an N-terminal side of the ALP.
A vector for Aspergillus transformation, comprising a nucleotide sequence encoding an ALP, wherein the nucleotide sequence includes a gene bound to a 5′-end side of the nucleotide sequence, the gene comprising any of following nucleotide sequences (a) to (c):
- (a) a nucleotide sequence set forth in any of SEQ ID NOs:
- 2 to 15;
- (b) a nucleotide sequence consisting of a nucleotide sequence formed from a nucleotide sequence set forth in any of SEQ ID NOs:
- 2 to 15 with deletion, substitution, or addition of one or several nucleotides and encoding a secretory signal peptide having ALP secretion activity;
- and
- (c) a nucleotide sequence having a homology of 90% or higher with a nucleotide sequence set forth in any of SEQ ID NOs:
- 2 to 15 and encoding a secretory signal peptide having ALP secretion activity;
- or
- a gene consisting of a nucleotide sequence encoding any of the following secretory signal peptides (d) to (f):
- (d) a secretory signal peptide consisting of an amino acid sequence set forth in any of SEQ ID NOs:
- 17 to 30;
- (e) a secretory signal peptide consisting of an amino acid sequence formed from an amino acid sequence set forth in any of SEQ ID NOs:
- 17 to 30 with deletion, substitution, or addition of one or several amino acids and having ALP secretion activity;
- and
- (f) a secretory signal peptide having a homology of 90% or higher with an amino acid sequence set forth in any of SEQ ID NOs:
- 17 to 30 and having ALP secretion activity.
