Our autoinhibitory coiled-coil output constructs
Taken and adapted from the JACS article 'An Autoinhibited Coiled-Coil Design Strategy for Split-Protein Protease Sensors' ref
The construct design is of the order:
Where in our case NFluc and CFluc will be NBlactamase CBlactamase//split eGFP and split TEV itself. The 2A refers to a mutated variation of the original coil sequence (AQLKKKLQANKKELAQLKWKLQALKKKLAQ)which produced a better coil activity.
Tobacco etch virus (TEV) protease-cleavable linker (GGGGENLYFQ- GGKLGGGG)was used.
