The present invention provides a bacterium which has an ability to produce a useful metabolite derived from acetyl-coenzyme A, such as L-glutamic acid, L-glutamine, L-proline, L-arginine, L-leucine, L-cysteine, succinate, and polyhydroxybutyrate, wherein said bacterium is modified so that activities of D-xylulose-5-phosphate phosphoketolase and / or fructose-6-phosphate phosphoketolase are enhanced. The present invention also provides a method for producing the useful metabolite using the bacterium.

The present invention provides materials and methods for pest control. The subject invention provides pesticidal compositions that contain one or more compounds that interact with organic solute transporter / ligand-gated ion channel multifunction polypeptides in the pest. Upon exposure to a target pest, these compositions either compromise pest growth and / or cause the death of the pest. In a preferred embodiment, the compositions of the subject invention contain one or more amino acids and / or amino acid analogs. In a particularly preferred embodiment, the methods of the subject invention involve exposing a pest to a composition that comprises methionine or leucine, or an analog thereof.

Charged nutritive proteins are provided. In some embodiments the nutritive proteins an aqueous solubility of at least 12.5 g / L at pH 7. In some embodiments the nutritive proteins an aqueous solubility of at least 50 g / L at pH 7. In some embodiments the nutritive proteins an aqueous solubility of at least 100 g / L at pH 7. In some embodiments the nutritive proteins comprise at least one of a level of a) a ratio of branch chain amino acid residues to total amino acid residues present in the nutritive protein equal to or greater than the ratio of branch chain amino acid residues to total amino acid residues present in a benchmark protein; b) a ratio of leucine residues to total amino acid residues present in the nutritive protein equal to or greater than the ratio of leucine residues to total amino acid residues present in a benchmark protein; and c) a ratio of essential amino acid residues to total amino acid residues present in the nutritive protein equal to or greater than the ratio of essential amino acid residues to total amino acid residues present in a benchmark protein. Also provided are nucleic acids encoding the proteins, recombinant microorganisms that make the proteins, methods of making the proteins using recombinant microorganisms, compositions that comprise the proteins, and methods of using the proteins, among other things.
