  • Publication number: 20070298050
    Abstract: Methods and compositions are disclosed to engineer chloroplast comprising heterologous mammalian genes via a direct replacement of chloroplast Photosystem II (PSII) reaction center protein coding regions to achieve expression of combinant protein above 5% of total protein. When algae is used, algal expressed protein is produced predominantly as a soluble protein where the functional acitivity of the peptide is intact. As the host algae is edible, production of biologics in this organism for oral delivery or proteins/peptides, especially gut active proteins, without purification is disclosed.

  • Patent number: 6294653
    Abstract: The present invention relates to recombinant protein disulfide isomerase, RB60, that functions as a translational regulator of the binding of a translational activator protein, RB47, to its binding site for the activation of translation. The recombinant RB60 protein is useful in a gene expression system in eukaryotic and prokaryotic cells, preferably plant cells and intact plants.

  • Patent number: 6156517
    Abstract: The present invention relates to a gene expression system in eukaryotic and prokaryotic cells, preferably plant cells and intact plants. In particular, the invention relates to an expression system having a RB47 binding site upstream of a translation initiation site for regulation of translation mediated by binding of RB47 protein, a member of the poly(A) binding protein family. Regulation is further effected by RB60, a protein disulfide isomerase. The expression system is capable of functioning in the nuclear/cytoplasm of cells and in the chloroplast of plants. Translation regulation of a desired molecule is enhanced approximately 100 fold over that obtained without RB47 binding site activation.
