  • Patent number: 6274743
    Abstract: Butane-1,4-diol, gamma-butyrolactone or tetrahydrofuran are prepared by vapor phase hydrogenation of a C4-dicarboxylic acid derivative. A maleic anhydride containing vapor stream is contacted in an absorption zone with a first high boiling solvent. A waste gas stream is passed to a scrubbing zone containing a second, higher boiling solvent. The waste gas is purged and the first and second solvents are recovered and recycled. Maleic anhydride is obtained from the absorption zone and converted to a maleic acid diester, which is stripped from the first solvent with hydrogen. The desired products are obtained by hydrogenation.

  • Patent number: 6271341
    Abstract: Transcriptional activators which differ in their activation potential by more than 3 orders of magnitude are provided. The transactivators are fusions between a DNA binding protein (e.g., a Tet repressor) and minimal transcriptional activation domains derived from Herpes simplex virus protein 16 (VP16). Substitution mutations at amino acid position 442 within the minimal VP16 domain provide transactivators with differing transactivation ability. Moreover, chimeric activation domains comprising both wild type and mutant minimal VP16 domains provide additional variants with differing transactivation ability. Various aspects of the invention pertain to nucleic acid molecules, vectors, host cells, fusion proteins, transgenic and homologous recombinant organisms and methods of regulating gene transcription.

  • Patent number: 6271345
    Abstract: An enzyme cleavable linker is prepared on which organic compounds are synthesized when the linker is bound to a solid phase. The linker contains a functional group on which a synthesized organic compound is bound when synthesis takes place, and a recognition site for a hydrolytic enzyme. Reacting the linker with the enzyme causes the linker to fragment at a site different from the recognition site to liberate the synthesized organic compound. The solid phase may be a crosslinked polyacrylamide containing an amino group for attaching the linker, and the linker is bound to the solid phase via a spacer. The spacer is attached to the solid phase by an ester, ether, amide or amine linkage, or a sulfide or phosphate linkage. In a specific reaction of forming a solid phase containing the linker, 2-acetoxy-5-hydroxymethylbenzoic acid is attached to an amino group-containing polymer via a spacer followed by conversion to a chloroformic ester.
