摘要:
A nucleotide sequence is provided which encodes a peptide having beta-xylosidase activity and exhibits at least 30 % amino acid identity with the amino acid sequence shown in SEQ ID NO. 1 or hybridises under stringent conditions with a nucleotide sequence shown in SEQ ID NO. 1, or a part thereof having at least 15 nucleotides encoding an amino acid sequence shown in SEQ ID NO. 1. Also provided is a peptide having beta-xylosidase activity and exhibiting at least 30 % amino acid identity with the amino acid sequence shown in SEQ ID NO. 1 or a part thereof having at least 8 amino acids shown in SEQ ID NO. 1. SEQ ID NO. 1 is derived from Aspergillus niger.
摘要:
The invention relates to a filamentous fungal cell (e.g., Aspergillus sp.) comprising at least one inactivated protease gene chosen from apsB, a homolog of apsB, cpsA, a homolog cpsA, and combinations thereof. Nucleic acids and methods for making the inactivated mutant filamentous fungal cells are provided as well as methods for using the cells for the altered production of endogenous or heterologous proteins of interest.
摘要:
Disclosed are compositions and methods relating to variant alpha-amylases. The variant alpha-amylases are useful, for example, for starch liquefaction and saccharification, for cleaning starchy stains in laundry, dishwashing, and other applications, for textile processing (e.g., desizing), in animal feed for improving digestibility, and for baking and brewing.
