J23119-BBa_B0034- POI -Spycatcher- BBa_B1006
Plug-and-Play Protein Assembly Module
Description:
This part enables us to produce proteins with functional SpyCatcher tags, which can bind to the scaffold proteins produced by BBa_K5461000, thereby enhancing the binding efficiency between the protein of interest (POI) and bacterial cellulose.
We used the common iGEM promoter J23119, RBS BBa_B0034, terminator BBa_B1006, and a SpyCatcher. Additionally, we designed a standard BsaI interface upstream of the SpyCatcher (GGTAAGAGACC - POI - GGTCTCATACCa), making it easy to replace the POI and generate various functional proteins that can be used for bacterial cellulose modification. Future iGEM teams can leverage this system to attempt various modifications to bacterial cellulose, and they could even perform high-throughput screening by replacing a library of POIs.
Results:
In this project, we utilized two colored proteins, sfGFP and amilCP, to complete the proof of concept (POC).
We successfully expressed the SpyCatcher-tagged sfGFP and amilCP fluorescent proteins and confirmed their expression and purification through SDS-PAGE molecular weight comparison and Western Blot (WB) analysis.
Next, we purified Curlis-SpyTag using the BBa_K5461000. After obtaining the purified Curlis-SpyTag, we validated the binding between bacterial cellulose, the Curlis-SpyTag scaffold protein, and the SpyCatcher-POI. The results demonstrated that the scaffold protein system significantly enhances the binding efficiency between the target protein (POI) and cellulose.
Through this demonstration, we successfully validated the efficiency of the Curlis-Spy scaffold protein design and the plug-and-play nature of the system. In the future, we plan to provide more protein data.
Summary:
We have established a standard, offering a foundational and scalable platform that decouples protein functionality from its compatibility with cellulose. This allows future iGEM teams to focus on selecting proteins for cellulose modification without needing to worry about their binding capability to cellulose, providing a foundational framework for the development of functionalized cellulose.
