摘要:
Variants of B. licheniformis alpha-amylase exhibit improved enzymatic performance, including increased themostability and reduced calcium dependence. Compositions comprising the variants are useful in methods of starch processing, starch liquefaction, fermatation, starch saccharification, cleaning, laundrying, textile desizing, baking, and biofilm removal. The nucleic acids encoding the variants are also disclosed.
摘要:
An alpha amylase from Bacillus subtilis (AmyE) produces significant amounts of glucose from various carbohydrate substrates, including vegetable starch, maltoheptaose, and maltotriose. Among other things, this advantageous property allows AmyE or variants thereof to be used in a saccharification reaction having a reduced or eliminated requirement for glucoamylase. The reduction or elimination of the glucoamylase requirement significantly improves the efficiency of the production of ethanol or high fructose corn syrup, for example.
摘要:
The present invention relates to modified variant Bowman Birk Protease Inhibitor proteins (BBPIs) that comprise peptides that bind target proteins, and that are further modified to have greater protease inhibitory activity and/or be produced at greater yields than the unmodified BBPIs. The invention encompasses polynucleotide constructs and expression vectors containing polynucleotide sequences that encode the modified variant BBPIs, the transformed host cells that express and produce the modified variant BBPIs, the modified variant BBPI proteins, the compositions comprising the modified variant BBPIs, and the methods for making and using the modified variant BBPIs in personal care.
摘要:
Disclosed are compositions comprising variants of a parent G. stearothermophilus alpha-amylase that have alpha-amylase activity and which exhibit altered properties relative to a parent AmyS-like alpha-amylase from which they are derived. The compositions comprise an additional enzyme such as a phytase. Also disclosed are methods of using the compositions, and kits related thereto.
