Abstract: A method for producing a mutant glucosidase includes introducing DNA encoding a secretion signal sequence and DNA encoding Asn-X-Ser or Asn-X-Thr into DNA encoding a glucosidase derived from a thermophile, and introducing the resulting DNA into a eukaryotic microorganism and expressing it as a secretory protein. An enzyme composition contains the mutant glucosidase.
Abstract: Compositions and methods are provided for enzymes with altered properties that involve a systematic approach to mutagenesis and a screening assay that permits selection of the desired proteins. Embodiments of the method are particularly suited for modifying specific properties of restriction endonucleases such as star activity. The compositions includes restriction endonucleases with reduced star activity as defined by an overall fidelity index improvement factor.

Abstract: Disclosed is a modified glucose dehydrogenases that has dramatically increased productivity in Escherichia coli and dramatically increased thermal stability, which is obtained by introducing specific amino acid mutations to glucose dehydrogenase derived from Botryotinia fuckeliana. Also disclosed is a modified glucose dehydrogenases that has dramatically increased productivity in E. coli and dramatically increased thermal stability, which is obtained by replacing two amino acid residues in glucose dehydrogenase of fungal origin with cysteine residues. The novel glucose dehydrogenase has a low reactivity to xylose.
Abstract: S-abscisic acid is used for promoting fruit set and/or for producing parthenocarpic fruits in useful plants. S-abscisic acid is also used as a growth inhibitor in useful plants. Methods are provided for treating useful plants with S-abscisic acid for these purposes.

Abstract: The invention relates to processes and biocatalysts for producing ethanol and other useful products from biomass and/or other materials. Initial processing of lignocellulosic biomass frequently yields methylglucuronoxylose (MeGAX) and related products which are resistant to further processing by common biocatalysts. Strains of Enterobacter asburiae are shown to be useful in bioprocessing of MeGAX and other materials into useful bioproducts such as ethanol, acetate, lactate, and many others. Genetic engineering may be used to enhance production of desired bioproducts.

Abstract: An environmentally compatible, selective herbicidal composition is provided that includes an activator adjuvant for enhancing the efficacy of the composition. While the activator adjuvant can be used in combination with a variety of herbicides, in an exemplary embodiment the herbicidal composition includes a metal chelate that is formed from a transition metal component and at least one chelating agent. The activator adjuvant can enhance, even synergistically effect the efficacy of the composition, while maintaining the selectivity of the herbicide.
