    摘要: The present invention relates to a preparation method using a fusion expression partner. The method includes preparing a polynucleotide encoding a fusion expression partner selected from the group consisting of SlyD (FKBR-type peptidyl prolyl cis-trans isomerase), Crr (glucose-specific phosphotransferase (PTS) enzyme IIA component), RpoS (RNA polymerase sigma factor), PotD (Spermidine/putrescine-binding periplasmic protein), and RpoA (RNA polymerase alpha subunit), and an expression vector linking a polyDNA fragment of a heterologous protein, preparing a transformant by introducing the expression vector into a host cell, inducing the expression of a recombinant protein by culturing a transformant, and obtaining the expression. In the preparation method of the recombinant protein, the heterologous protein may enhance the water-solubility and folding of the recombinant protein, overcome the limitations about the water-solubility and folding which the conventional fusion expression partners have, and be used widely in the production of pharmaceutical and industrial proteins.

    摘要: A recombinant fluorescent protein nanoparticle having high fluorescence intensity and a method of detecting a target material using the same are provided. The protein nanoparticle has higher fluorescence intensity than a fluorescent protein, and is resistant to denaturation of the fluorescent protein at room temperature, thereby having higher structural stability than the fluorescent protein itself. In addition, since a self-assembled protein is used as a fusion partner of the fluorescent protein, the protein nanoparticle is biocompatible and safe. Moreover, when a linker peptide is additionally inserted into the protein nanoparticle, a suitable distance between the self-assembled protein and the fluorescent protein is maintained, thereby considerably increasing fluorescence intensity of the protein nanoparticle. The probe-binding protein nanoparticle can control distances between the fluorescent proteins on the surface thereof, thereby maximizing fluorescence intensity.
