    摘要: This invention provides stable aqueous compositions including stable coating compositions, and methods of their production. The stable aqueous compositions and stable aqueous coating compositions comprise one or more emulsion-polymerized addition polymer, one or more carboxylesterase enzyme, and one or more carboxylesterase deactivating agent, such that the ester hydrolysis activity in the composition is less than 0.010 micromole/minute, and wherein the aqueous composition has a headspace volatile organic compound (VOC) content, as measured by headspace gas chromatography-mass spectrometry (GC-MS) at 33° C., of less than 10 ppm of organic carboxylester with a normal boiling point of less than 150° C. and more than 50 ppm of mono-alcohol with a formula molecular weight of less than 76. The carboxylesterase enzyme is employed to minimize the free carboxylester content in the composition, thereby providing a low odor composition, and the carboxylesterase is deactivated in situ in order to minimize the residual carboxylesterase enzyme activity.

    摘要: Novel synthases and the corresponding nucleic acids encoding such synthases are disclosed herein. Such synthases possess an active site pocket that includes key amino acid residues that are modified to generate desired terpenoid reaction intermediates and products. Synthase modifications are designed based on, e.g., the three-dimensional coordinates of tobacco 5-epi-aristolochene synthase with or without a substrate bound in the active site.
