  • Publication number: 20140213758
    Abstract: Novel methods of native chemical ligation are provided. The methods involve reacting a thioacid (e.g. a peptide thioacid) with an aziridinyl compound (e.g. an aziridinyl peptide) or glycosylamine under mild conditions without the use of protecting groups, and without requiring that a cysteine residue be present in the ligation product. Initial coupling of the thioacid and the aziridinyl compound yields a ligation product containing an aziridinyl ring. Optional subsequent opening of the aziridinyl ring (e.g. via a nucleophilic attack) produces a linearized and modified ligation product. Coupling of a peptide thioacid and glycosylamine yields a glycosylated peptide.

  • Patent number: 8791327
    Abstract: The amino acid and nucleic acid sequences of a ?5-desaturase enzyme and a ?8-desaturase enzyme are disclosed. The nucleic acid sequences can be used to design recombinant DNA constructs and vectors. These vectors can then be used to transform various organisms, including for example, plants and yeast. The transformed organisms will then produce polyunsaturated fatty acids. The amino acid sequences are useful for generating enzyme-specific antibodies that are useful for identifying the desaturases.

  • Patent number: 8784842
    Abstract: Particular aspects provide efficient allelic exchange methods to generate directed mutations within genes of slow-growing stains of mycobacteria (e.g., Mycobacterium avium subsp. paratuberculosis (Map), Map 10 or GFP-expressing Map K-10) using a phage-delivery system, and demonstrate high efficiency allelic exchange. Additional exemplary aspects provide non-naturally occurring slow-growing strains of mycobacteria (e.g., Map, M. bovis, M. tuberculosis) having at least one gene deletion (e.g., pknG, relA, lsr2, panC, panD, proC, trpD, sapM (MAP3432), lysA_1, leuD, and leuC, and deletion mutants at the orthologous loci of two known virulence genes in pathogenic mycobacteria (relA and pknG) and one gene related to colony morphology and biofilm formation in fast growing mycobacteria (lsr2) were made. Further aspects provide novel vaccines comprising such deletion mutants, or portions thereof, and methods for making said vaccines. Yet further aspects provide methods for protecting a mammal from virulent Map, M.

  • Publication number: 20140137298
    Abstract: A 23 amino acid peptide, AtPep1, plays an important role as a signaling component of the innate immune system of Arabidopsis. The peptide precursor gene is transcribed in response to elicitors generated by pathogens, and AtPep1 is produced to amplify the signaling pathways. Seven paralogs of the AtproPep1 gene have been identified in the Arabidopsis genome, and orthologs have been identified in species of several agriculturally important families. AtPep1 and its paralogs and orthologs play important roles as endogenous signals to amplify innate immunity. The sequences of two AtPep1 receptors from Arabidopsis are also provided.
