Abstract: Compositions and methods for improved cell-based methods of characterizing botulinum neurotoxins are provided. Cells utilized in these methods include a reporting construct that is cleaved following uptake and processing of botulinum neurotoxin by the cell, resulting in proteolysis of the portion of the reporting construct that is released following cleavage. The released portion includes a fluorophore and amino acid substitutions or sequences that enhance the rate of proteolysis. A pair of reporting constructs can be utilized in which one member of the pair is modified to resist cleavage by the botulinum neurotoxin while co-localizing with the remaining member of the pair.

Abstract: The biological production of beta-hydroxyisovalerate (?HIV) using a non-natural microorganism. The non-natural microorganism for the biologically-derived ?HIV provides more beta-hydroxyisovalerate synthase activity than the wild-type parent. The non-natural microorganism can host a non-natural enzyme, such as the non-natural enzyme expressed in a yeast or bacteria, wherein the non-natural microorganism comprises an active ?HIV metabolic pathway for the production of ?HIV. The biological derivation of ?HIV eliminates toxic by-products and impurities that result from the chemical production of ?HIV, such that ?HIV produced by a non-natural microorganism prior to any isolation or purification process has not been in substantial contact with any halogen-containing component.

Abstract: The invention includes an orally ingestible delivery system for releasing a therapeutic agent within an intestine of a mammal, where the system includes the therapeutic agent and a differentially permeable capsule system containing the therapeutic agent within a therapeutic agent compartment, with the differentially permeable capsule system dimensionally adapted for oral ingestion and for passage into a stomach of the mammal and thence into the intestine, wherein the differentially permeable capsule system comprises an acid-resistant shell and a dispersible acid barrier, wherein the dispersible acid barrier forms while the orally-ingestible delivery system is in the stomach; and wherein the dispersible acid barrier is dispersed in the intestine, thereby permitting enzymes in the intestine to reach the therapeutic agent compartment. The invention also includes methods of manufacturing the system and methods for its use.
