    Abstract: Provided herein are methods and systems for codon rewriting and replacement. In some aspects, provided herein, is a method comprising: analyzing at least a portion of a genome of an organism to identify a first plurality of codons based on at least in part on a first local context of a codon-of-interest in the genome of the organism to be rewritten; and rewriting the first plurality of codons in the genome of the organism to a second codon.

  • Patent number: 10865417
    Abstract: Provided are compositions and methods for compound discovery. Modified yeast that have their endogenous yeast shikimate pathway disrupted or deleted, and replaced with homologous pathway genes from one or more distinct organisms, are provided and used in assays of test agents. The homologous pathway genes are designed to supplement the disrupted or deleted shikimate pathway genes. The assays are designed to identify whether or not the test agents can interfere with the function of enzymes in the shikimate pathway from organisms that are distinct from the yeast avatar hosts. In embodiments, the disruption/deletion of the yeast endogenous shikimate pathway results in the yeast being incapable of producing chorismic acid.

  • Publication number: 20030190332
    Abstract: A vaccine produced in edible plant and/or animal products, as well as a method of second-generation vaccine development through the production of at least one complete structure of a pathogen in a transgenic plant or animal is described. Preferably, the present invention enables the production of virus-like particles in edible food plants, through the co-expression of a plurality of proteins and/or of a plurality of portions of such proteins. The co-expression of viral structural proteins should enhance the immunogenicity of the transgenic antigen by providing all elements necessary to induce a protective immune response. In one variation of the method the immune response to the transgenic vaccine would be induced by presenting the transgenic proteins as part of an edible plant structure, utilizing this to stimulate the mucosal immune system. Alternatively, the vaccine produced in transgenic plant/animal products could be purified and used as an immunogen in other vaccination strategies.
