    Abstract: Novel alpha-amylase mutants derived from the DNA sequences of naturally occurring or recombinant alpha-amylases are disclosed. The mutant alpha-amylases, in general, are obtained by in vitro modifications of a precursor DNA sequence encoding the naturally occurring or recombinant alpha-amylase to generate the substitution (replacement) or deletion of one or more oxidizable amino acid residues in the amino acid sequence of a precursor alpha-amylase. Such mutant alpha-amylases have altered oxidative stability and/or altered pH performance profiles and/or altered thermal stability as compared to the precursor. Also disclosed are detergent and starch liquefaction compositions comprising the mutant amylases, as well as methods of using the mutant amylases.

    Abstract: 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.

    Abstract: Chimeric alpha amylases having the characteristics of high thermostability and good performance in starch degradation, especially high-temperature liquefaction processes, are provided. The alpha-amylases are chimeras of AmyL and AmyS enzymes, and are useful in starch degradation processes. Methods of making the chimeric enzymes, and methods of using the chimeric alpha-amylases for liquefaction, cleaning starch residue from a surface, and treating woven material to remove coatings. Kits for practicing the methods are provided. Polynucleotides encoding the chimeric amylases, vectors, and expression hosts also are provided.
