摘要:
A method of making a Bacillus alpha-amylase variant that increases alpha-amylase production and the alpha-amy-lases produced thereby. The recombinant alpha-amylases can be placed in compositions and used for purposes of laundry detergents, cleaning and dishwashing detergents, fabric desizing, starch liquefaction, cereal liquefaction, starch saccharification, biofilm removal, and starch hydrolysis in cane sugar processing.
摘要:
The present disclosure relates to variants of a parent glucoamylase having altered properties (e.g., improved thermostability and/or specific activity). In particular, the present disclosure provides compositions comprising the variant glucoamylases, including starch hydrolyzing compositions and cleaning compositions. The disclosure also relates to DNA constructs encoding the variants and methods of producing the glucoamylase variants in host cells.
摘要:
Disclosed herein are compositions comprising an alpha-amylase enzyme obtained from Bacillus sp. no. 195, and methods of using the enzyme to clean surfaces and textiles. Also disclosed are variants of the enzyme with different signal sequences.
摘要:
The present invention relates to glucoamylase variants. In particular, the invention relates to variants in the starch binding domain (SBD) of a glucoamylase. The invention also relates to variants having altered properties (e.g., improved thermostability and/or increased specific activity) as compared to a corresponding parent glucoamylase. The present invention also provides enzyme compositions comprising the variant glucoamylases; DNA constructs comprising polynucleotides encoding the variants; and methods of producing the glucoamylase variants in host cells.

摘要:
Disclosed are variants of the α-amylase derived from Bacillus sp. no. 707, compositions comprising said variants, compositions comprising the variants, and methods of using the variants. The methods of use include methods of cleaning surfaces, laundering textiles, desizing, hydrolyzing biofilms off various substrates, and treating starch (e.g., liquefaction and saccharification).
摘要:
The present invention relates to variant glucoamylases wherein the variant has altered properties (e.g., improved thermostability and/or specific activity) compared to a corresponding parent glucoamylase. The present invention also relates to enzyme compositions comprising a variant glucoamylase (e.g., starch hydrolyzing compositions); DNA constructs comprising polynucleotides encoding the variants and methods of producing the variant glucoamylases in host cells.
摘要:
The invention relates to novel variants of the enzymatic peptide pullulanase, the gene sequences encoding said novel peptides, expression vectors comprising those gene sequences as well as organisms expressing the novel pullulanase variants. The novel pullulanase variants of the present invention were made empirically by the use of codon-optimization procedures, selective truncation of “wild-type” molecules and through the replacement of selected amino acid residues. Furthermore, the invention relates to the use of these novel pullulanase peptides in the textile, fermentation, food and other industries.
