CL7-linker-sfGFP_Green fluorescent protein and CL7 complex

CL7 is is a protein tag engineered from colicin CE7. In E.coli, CE7 is a bacteriocin that belongs to the colicin DNase family and has endonuclease activity. Through engineering, CL7 removed DNA binding and catalytic activity, but retained its high affinity binding ability to the corresponding inhibitory protein Im7. This property makes CL7 a useful tool for protein purification and molecular biology applications.
Linker here is used to connect CL7 and sfGFP short peptide sequence.
sfGFP, namely the super folding green fluorescent protein (Superfolder GFP), is a genetically engineered green fluorescent protein (GFP) variations.
In the experimental design, we took advantage of the high affinity between CL7 and Im7 and incubated CL7-Linker-SFGFP to bind to Inak-linker-Im7(another composite part we registered), thus anchoring the integrated system to the membrane surface. Finally, the Inak-linker-Im7-CL7-linker-sfGFP system was demonstrated on the membrane surface, where the function of sfGFP protein was tested by double fluorescence verification (see the experimental design section for details) to see whether the system was successfully displayed on the membrane surface. It should be noted that the system we designed uses the high affinity of CL7 and Im7, so some components can be flexibly replaced according to needs, and are suitable for different use scenarios according to different needs. For example, according to different cells to replace the ice nucleated protein, according to different targeting targets to replace sfGFP with different single-chain antibodies, nano antibodies and so on.

-CL7 is is a protein tag engineered from colicin CE7. In E.coli, CE7 is a bacteriocin that belongs to the colicin DNase family and has endonuclease activity. Through engineering, CL7 removed DNA binding and catalytic activity, but retained its high affinity binding ability to the corresponding inhibitory protein Im7. This property makes CL7 a useful tool for protein purification and molecular biology applications. Would here is used to connect CL7 and sfGFP short peptide sequence. SfGFP, namely the super folding green fluorescent protein (Superfolder GFP), is a genetically engineered green fluorescent protein (GFP) variations. Formed by the union of the three series of composite parts, mainly through the CL7 and Im7 high affinity ability, through the incubation makes CL7 - would - sfGFP and Inak - would - Im7 (we register another composite components), and anchor integration system in the membrane surface. Finally, the Inak-linker-Im7-CL7-linker-sfGFP system was displayed on the surface of the membrane, so that sfGFP protein could play a role. Here, the role of sfGFP protein was tested by double fluorescence verification whether the system was successfully displayed on the membrane surface. It should be noted that the system we designed uses the high affinity of CL7 and Im7, so some components can be flexibly replaced according to needs, and are suitable for different use scenarios according to different needs. For example, according to different cells to replace the ice nucleated protein, according to different targeting targets to replace sfGFP with different single-chain antibodies, nano antibodies and so on.
