  • Patent number: 7582426
    Abstract: The present invention relates to a method for display of proteinson spore surface and a method for improving protein with rapidity using the same, which comprises the steps of (i) preparing a vector for spore surface display comprising a gene construct containing a gene encoding spore coat protein and a gene encoding a protein of interest, wherein, when expressed, the gene construct expresses a fusion protein between the spore coat protein and the protein of interest, (ii) transforming a host cell with the vector for spore surface display; (iii) displaying the protein of interest on a surface of a spore of the host cell; and (iv) recovering the spore displaying on its surface the protein of interest.

  • Publication number: 20040180348
    Abstract: The present invention relates to methods for preparing a protein of interest surface-displayed on genetic carrier, for improving a protein of interest, for isolating a substance of interest, bioconversion and producing antibody. More particularly, the present invention relates to a method for preparing a protein of interest surface-displayed on genetic carrier, which comprises the steps of: (a) transforming a host cell harboring the genetic carrier selected from the group consisting of spore and virus with a vector containing a gene encoding the protein of interest; (b) culturing the transformed host cell and expressing the protein of interest in the host cell; and (c) allowing to form noncovalent bond between the expressed protein and a surface of the genetic carrier so that the protein of interest is displayed on the surface of the genetic carrier.
