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.
摘要翻译：提供具有高荧光强度的重组荧光蛋白纳米颗粒和使用其的目标材料的检测方法。蛋白质纳米颗粒具有比荧光蛋白更高的荧光强度，并且在室温下对荧光蛋白质的变性具有抗性，因此具有比荧光蛋白本身更高的结构稳定性。另外，由于使用自组装蛋白作为荧光蛋白的融合配偶体，所以蛋白质纳米颗粒是生物相容性和安全性的。此外，当连接肽另外插入到蛋白质纳米颗粒中时，维持自组装蛋白和荧光蛋白之间的适当距离，从而显着增加蛋白质纳米颗粒的荧光强度。探针结合蛋白纳米颗粒可以控制其表面上的荧光蛋白之间的距离，从而使荧光强度最大化。
