摘要:
The present invention relates to isolated polypeptides having cellobiohydrolase activity and isolated polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.
摘要:
The present description is related to the field of protein production. It introduces novel host cells with low protease activity, a novel protease regulator, its use in expression systems and protein production, and a method of producing host cells for protein production
摘要:
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.
摘要:
The present invention relates to a polypeptide which has ²-glucosidase activity, and which includes an amino acid sequence represented by SEQ ID NO: 1, a polypeptide including an amino acid sequence in which one or several amino acids are deleted, substituted, or added in the amino acid sequence represented by SEQ ID NO: 1, or a polypeptide including an amino acid sequence having 92% or greater sequence identity with the amino acid sequence represented by SEQ ID NO: 1. According to the present invention, a novel ²-glucosidase enzyme derived from Acremonium cellulolyticus, a polynucleotide encoding the ²-glucosidase, an expression vector for expressing the ²-glucosidase, a transformant incorporated with that expression vector, and a method for producing a cellulose degradation product using the ²-glucosidase can be provided.
摘要:
The present invention relates to a cell suitable for production of one or more fermentation product from a sugar composition comprising glucose, galactose, arabinose and xylose, wherein the cell comprises two to fifteen copies of one or more xylose isomerase gene or two to fifteen copies of one or more xylose reductase and xylitol dehydrogenase, and two to ten copies of araA, araB and araD, genes, wherein these genes are integrated into the cell genome.
