IPTG induced promoter + GFP with a His-tag fused to a coiled coil
GFP with His tag at the C-terminus and the E-coil at the N-terminus behind an IPTG induced promoter to use it as reporter for the E- and K-coil [http://2012.igem.org/Team:Wageningen_UR/Coil_system Plug and Apply system]
Usage and Biology
The E-coil present in this reporter protein is one part of the Plug and Apply (PnA) system consisting of a combination of E- and K-coil. These coils consist of α-helical repeats and have a strong affinity to each other due to electrostatic interactions (with K-coil positively charged and E-coil negatively charged). Using this system one can bind two proteins noncovalently but specifically to each other. This brick can be used for confirmation of the Plug and Apply system using E- and K-coils as well as for detection of proteins that can be fused to the K-coil.
To be able to use the device, the counterpart of the E-coil needs to be fused to the protein that needs to be detected.
