  • Patent number: 7238507
    Abstract: The present invention relates to a novel cytochrome P450-like enzyme (Aspergillus ochraceus 11 alpha hydroxylase) and an oxidoreductase (Aspergillus ochraceus oxidoreductase) isolated from cDNA library generated from the mRNA of Aspergillus ochraceus spores. When the cDNA encoding the 11 alpha hydroxylase was co-expressed in Spodoptera frugiperda (Sf-9) insect cells with the cDNA encoding human oxidoreductase as an electron donor, it successfully catalyzed the conversion of the steroid substrate 4-androstene-3,17-dione (AD) to 11 alpha-hydroxy-AD as determined by HPLC analysis. The invention also relates to nucleic acid molecules associated with or derived from these cDNAs including complements, homologues and fragments thereof, and methods of using these nucleic acid molecules, to generate, for example, polypeptides and fragments thereof. The invention also relates to the generation of antibodies that recognizes the A.

  • Patent number: 7229804
    Abstract: The gene encoding a 4-hydroxybutyryl-CoA transferase has been isolated from bacteria and integrated into the genome of bacteria also expressing a polyhydroxyalkanoate synthase, to yield an improved production process for 4HB-containing polyhydroxyalkanoates using transgenic organisms, including both bacteria and plants. The new pathways provide means for producing 4HB containing PHAs from cheap carbon sources such as sugars and fatty acids, in high yields, which are stable. Useful strains are obtaining by screening strains having integrated into their genomes a gene encoding a 4HB-CoA transferase and/or PHA synthase, for polymer production. Processes for polymer production use recombinant systems that can utilize cheap substrates. Systems are provided which can utilize amino acid degradation pathways, ?-ketoglutarate, or succinate as substrate.

  • Patent number: 7205136
    Abstract: A method for increasing the rate of chemical reactions involving the conversion of at least one reactant to at least one product involves contacting the reactant with an appropriate monoclonal antibody under conditions permitting the formation of a complex between the antibody and the reactant. The complexed reactant is converted to the product which is then released from the complex. The monoclonal antibody may employ a cofactor and may be directed to a known substrate of an enzyme. Methods for preparing such monoclonal antibodies are also disclosed.

  • Patent number: 7189503
    Abstract: The invention relates to a method for detecting a double-stranded region in a nucleic acid by (1) providing two separate, adjacent pools of a medium and a interface between the two pools, the interface having a channel so dimensioned as to allow sequential monomer-by-monomer passage of a single-stranded nucleic acid, but not of a double-stranded nucleic acid, from one pool to the other pool; (2) placing a nucleic acid polymer in one of the two pools; and (3) taking measurements as each of the nucleotide monomers of the single-stranded nucleic acid polymer passes through the channel so as to differentiate between nucleotide monomers that are hybridized to another nucleotide monomer before entering the channel and nucleotide monomers that are not hybridized to another nucleotide monomer before entering the channel.

  • Patent number: 7169596
    Abstract: This invention provides a novel isolated polynucleotide sequence, called ADARP1 (adenosine deaminase related protein 1), that displays significant homology to the adenosine deaminase (ADA) gene. Also provided is the amino acid sequence of the ADARP1 polypeptide encoded by the polynucleotide of the invention. The RNA for this novel gene is found in variety of tissues, with higher levels observed in the heart, testes, and skeletal muscle compared with others tested.
