  • Patent number: 10626405
    Abstract: To provide a base sequence for protein expression that can increase the yield of protein such as diastatic enzyme by further activating a promoter of a particular gene. A base sequence 1 for protein expression includes: a gene 3 encoding protein 2; a promoter 4 of the gene 3, the promoter being linked upstream of the gene 3; and a cis element 5 whose activity is improved by an artificial transcription factor 6, the cis element being linked further upstream of the promoter 4. The cis element 5 is represented by SEQ ID NO: 1.

  • Patent number: 9605249
    Abstract: An object of the invention is to provide cellobiohydrolase with high activity. The activity of cellobiohydrolase can be improved by substituting, with alanine, asparagine that is the amino acid at position 62 from the N-terminal of cellobiohydrolase shown in SEQ ID NO: 1, or asparagine at a position corresponding to the position 62 in an amino acid sequence corresponding to the sequence of the cellobiohydrolase shown in SEQ ID NO: 1.

  • Patent number: 9567563
    Abstract: Provided are an Aspergillus mutant strain which can dramatically enhance production of a heterologous enzyme when a saccharifying enzyme gene is transferred into the strain to perform transformation and a transformant having a saccharifying enzyme gene transferred into the Aspergillus mutant strain. The Aspergillus mutant strain has been completely or partially deficient in three genes of Aspergillus oryzae strain HO2 (accession number: NITE BP-01750): a prtR gene coding for a transcription factor; a pepA gene coding for an extracellular acid protease; and a cpI gene coding for an extracellular acid carboxypeptidase.
