    摘要: The present invention relates to novel mutant thioesterase enzymes and naturally-occurring equivalents thereof, compositions made from such enzymes and uses of thioesterase enzymes. In particular, the present invention provides mutant thioesterase enzymes that have altered properties, for example, altered substrate specificity, altered activity, altered selectivity, and/or altered proportional yields in the product mixtures. The present invention also provides polynucleotides encoding such mutant thioesterase enzymes, and vectors and host cells comprising such polynucleotides. The invention further provides for novel uses of thioesterases in the production of various fatty acid derivatives, which are useful as, or as components of, industrial chemicals and fuels.

    摘要: Modified proteins are disclosed that maintain enzymatic and insecticidal activity while displaying reduced or eliminated allergenicity. Epitopes which bind to anti-patatin antibodies were identified, and removed via site directed mutagenesis. Tyrosines were observed to generally contribute to the allergenic properties of patatin proteins. Removal of glycosylation sites was observed to reduce or eliminate antibody binding. Permuteins are also disclosed which have a rearranged amino acid sequence while retaining enzymatic activity. Deallergenized proteins and permuteins can be used as insecticidal materials, as nutritional supplements, and as immunotherapeutic agents.
