Evaluation Vector with PxylA to screen for protein specific secretion efficiency
The Evaluation Vector (EV) is part of both, the Evaluation Vector and the Signal Peptide Toolbox of the iGEM Team TU Dresden 2017 (EncaBcillus - It's a trap!).
The EV was developed with easily exchangeable units: I) allowing the replacement of the promoter (which drives the system) and II) a multiple cloning site enabling to work with translationally fused composite parts.
In summary, the EV was designed to fulfill the following distinct features:
- Exchangeable promoter region
- Insertion of basic or composite parts as expression units
- Fulfilling the RFC10 and RFC25 BioBrick standard
- Easy cloning and screening procedure in Escherichia coli
We constructed the Evaluation Vector (EV) to quickly screen for the secretion of a protein of interest. This vector contains a specifically designed multiple cloning site (MCS) equipped with reporters to quickly identify positive replacements by insert integration (Figure 1). Additionally, this vector can be applied for the expression of any other fusion protein of interest regulated by a promoter of your choice. For more details on the application check out our project.
In the case of the Signal Peptide Toolbox which was designed to increase protein secretion efficiency, a typical composite part consists of a signal peptide for secretion in bacteria (for example AmyE) and a protein of interest.
