20080274155Chimeric Cannulae Proteins, Nucleic Acids Encoding Them And Methods For Making And Using Them - The invention provides chimeric cannulae polypeptides and nanotubules and methods for making and using them. In one aspect, the invention provides compositions and methods for the identification, separation or synthesis of proteins or ligands. In one aspect, the invention provides compositions and methods for making and using nanotubules. In one aspect, the invention provides compositions and methods for the selection and purification of chiral compositions from racemic mixtures. In one aspect, the chimeric proteins and polymers (e.g., nanotubules, tubules, bundles, balls, fibers, filaments, sheets, threads, textiles) of the invention comprise a detectable moiety, e.g., a fluorescent protein. In one aspect, the invention provides a flame retardant or heat resistant device comprising a sheeting, a covering, a coating or an adhesive comprising a chimeric protein of the invention.11-06-2008
20080305531Compositions and Methods for Making and Modifying Oils - The invention provides novel methods for making or modifying oils, e.g., plant, animal or microbial oils, such as vegetable oils or related compounds, that are low in a particular fatty acid(s), for example, low linoleic oils, low linolenic oils, low palmitic oils, low stearic oils or oils low in a combination thereof.12-11-2008
20090155238XYLANASES, NUCLEIC ACIDS ENCODING THEM AND METHODS FOR MAKING AND USING THEM - The invention relates to enzymes having xylanase, mannanase and/or glucanase activity, e.g., catalyzing hydrolysis of internal β-1,4-xylosidic linkages or endo-β-1,4-ghicanase linkages; and/or degrading a linear polysaccharide beta-1,4-xylan into xylose. Thus, the invention provides methods and processes for breaking down hemicellulose, which is a major component of the cell wall of plants, including methods and processes for hydrolyzing hemicelluloses in any plant or wood or wood product, wood waste, paper pulp, paper product or paper waste or byproduct. In addition, methods of designing new xylanases, mannanases and/or glucanases and methods of use thereof are also provided. The xylanases, mannanases and/or glucanases have increased activity and stability at increased pH and temperature.06-18-2009
20090176976NITRILASES - The invention relates to nitrilases and to nucleic acids encoding the nitrilases. In addition methods of designing new nitrilases and method of use thereof are also provided. The nitrilases have increased activity and stability at increased pH and temperature.07-09-2009
20090297495HYDROLASES, NUCLEIC ACIDS ENCODING THEM AND METHODS FOR IMPROVING PAPER STRENGTH - The invention provides hydrolases, polynucleotides encoding them, and methods of making and using these polynucleotides and polypeptides. In one aspect, the invention is directed to polypeptides, e.g., enzymes, having a hydrolase activity, e.g., an esterase, acylase, lipase, phospholipase (e.g., phospholipase A, B, C and D activity, patatin activity, lipid acyl hydrolase (LAH) activity) or protease activity, including thermostable and thermotolerant hydrolase activity, and polynucleotides encoding these enzymes, and making and using these polynucleotides and polypeptides. The hydrolase activities of the polypeptides and peptides of the invention include esterase activity, lipase activity (hydrolysis of lipids), acidolysis reactions (to replace an esterified fatty acid with a free fatty acid), transesterification reactions (exchange of fatty acids between triglycerides), ester synthesis, ester interchange reactions, phospholipase activity and protease activity (hydrolysis of peptide bonds). In another aspect, the invention provides methods for hydrolyzing steryl esters and triglycerides (e.g., in a paper pulp), into sterols, glycerol and free fatty acids, using enzyme(s) of the invention. The invention provides enzymes and methods for decreasing the amount of lipophilic extracts (“pitch”) in a pulp-comprising composition. The polypeptides of the invention can be used in a variety of pharmaceutical, agricultural and industrial contexts, including the manufacture of cosmetics and nutraceuticals.12-03-2009
