  • Patent number: 11643643
    Abstract: The present invention pertains to a novel architecture of non-ribosomal peptide synthases (NRPS). The invention provides artificial NRPS wherein the naturally occurring terminal condensation or thioesterase-domain is replaced by internal condensation or dual condensation/epimerization domains. Moreover, the present invention enables the portability of terminal condensation domains to unrelated NRPS in respect of peptide release of linear peptides. The replacement results in a product independent release of the synthesized product and therefore enables the rational design of NRPS. The invention provides the new NRPS, nucleic acids encoding them, methods for artificial NRPS generation, and methods for producing non-ribosomal peptides.

  • Patent number: 11534500
    Abstract: Angelman Syndrome (AS) is a genetic disorder occurring in approximately one in every 15,000 births. It is characterized by severe mental retardation, seizures, difficulty speaking and ataxia. The gene responsible for AS was discovered to be UBE3A and encodes for E6-AP, an ubiquitin ligase. A unique feature of this gene is that it undergoes maternal imprinting in a neuron-specific manner. In the majority of AS cases, there is a mutation or deletion in the maternally inherited UBE3A gene, although other cases are the result of uniparental disomy or mismethylation of the maternal gene. While most human disorders characterized by severe mental retardation involve abnormalities in brain structure, no gross anatomical changes are associated with AS. We have generated a Ube3a protein with additional sequences that should allow the secretion from cells and uptake by neighboring neuronal cells. This would confer a functional E6-AP protein into the neurons and rescue disease pathology.

  • Patent number: 10941185
    Abstract: The present invention discloses a strain of bacteria producing DHA and/or EPA, six gene fragments in the bacterial genome, and uses thereof. The strain is Schizoochytrium limacinum HS01, which has the accession number of CGMCC No. 13746 at China General Microbiological Culture Collection Center. The six gene fragments are composed of gene fragment 1 to gene fragment 6, and the nucleotide sequences are sequentially as shown in SEQ ID NO: 3 to SEQ ID NO: 8 in the Sequence Listing. The experiments prove that fermentation broth containing DHA and EPA can be obtained by fermenting Schizoochytrium limacinum HS01; the recombinant strain is obtained by introducing gene fragment 1 to gene fragment 6 into Schizoochytrium limacinum MYA-1381; the ability the recombinant strain for producing DHA and EPA is greatly improved.

  • Patent number: 10934324
    Abstract: A method of improving protein functionality includes obtaining a protein such as protein contained within exclusion bodies contained within bacteria or yeast used for the recombinant expression of the protein. The exclusion bodies are solubilized using a chaotropic agent such as guanidine or urea. The protein is then subject to denaturation conditions and optionally purified. A liquid containing the denatured protein is loaded into a vessel that is angled relative to horizontal. The vessel is then rotated in the angled configuration at a rate within that is less than 10,000 RPM for period of time. Refolded protein is formed by the high shear conditions formed in the thin film of fluid formed in the inner surface of the rotating vessel. Refolding can be performed in a batch mode or a continuous mode. The process may be scaled up for industrial applications by using multiple vessels.
