    Abstract: The present invention relates to the intrathecal (IT) administration of recombinant enzyme to treat lysosomal storage disorders. In an exemplary embodiment, intrathecal administration of human ?-L-iduronidase (rhIDU) injections in MPS I affected animals resulted in significant enzyme uptake, significant rh-iduronidase activity in brain and meninges and a decrease of glycosaminoglycan (GAG) storage in cells of MPS I subjects to that of normal subjects. Intrathecal administration proved more effective than intravenous treatment at alleviating MPS I symptoms, indicating it is a useful method of treating lysosomal storage disorders.

    Abstract: The present invention relates to an isolated mutant eubacterium comprising at least one mutation resulting in a substitution of at least one amino acid in the beta-subunit of the RNA-polymerase encoded for by the rpoB-gene providing an altered production of a product of interest when said production of a product of interest is compared to the production of the same product in an isogenic wild type strain grown at identical conditions, wherein the substitution of at least one amino acid occurs at any of positions 469, 478, 482, 485, or 487 of SEQ ID NO:2, or at the equivalent positions in any eubacterial RNA-polymererase beta-subunit family member. Another aspect of the invention relates to a process for producing at least one product of interest in a mutant eubacterium and to a use of the mutant eubacterium according to the invention for producing at least one product of interest.

  • Publication number: 20130095553
    Abstract: The invention relates to a polypeptide which comprises the amino acid sequence set out in SEQ ID NO: 2 or an amino acid sequence encoded by the nucleotide sequence of SEQ ID NO: 1, or a variant polypeptide or variant polynucleotide thereof, wherein the variant polypeptide has at least 76% sequence identity with the sequence set out in SEQ ID NO: 2 or the variant polynucleotide encodes a polypeptide that has at least 76% sequence identity with the sequence set out in SEQ ID NO: 2. The invention features the full length coding sequence of the novel gene as well as the amino acid sequence of the full-length functional polypeptide and functional equivalents of the gene or the amino acid sequence. The invention also relates to methods for using the polypeptide in industrial processes. Also included in the invention are cells transformed with a polynucleotide according to the invention suitable for producing these proteins.

  • Publication number: 20130089910
    Abstract: Promoter regions associated with the Yarrowia lipolytica n-alkane-hydroxylating cytochrome P450 (ALK2) gene are disclosed and have been found to be particularly effective for the expression of heterologous genes in yeast. These promoter regions will be useful for driving high-level expression of genes involved in the production of omega-3 and omega-6 fatty acids.

  • Publication number: 20130064805
    Abstract: The present invention provides, as an enzyme which can be used for enzyme replacement therapy for Fabry disease, a protein having ?-galactosidase activity, which shows no allergic adverse side effect, shows a high stability in blood, and can be easily incorporated into a cell of an affected organ. The protein of the present invention is a protein which has acquired ?-galactosidase activity by changing the structure of the active site of wild-type human ?-N-acetylgalactosaminidase.
