Coding
Part:BBa_K1965045
Designed by: Katja Leben Group: iGEM16_Slovenia (2016-10-17)
cLuc:A:HA
This construct consists of the C-terminal part of the split luciferase attached to the coiled coil A. The sequence for the coiled coil A was taken from the Shekhawat et al. (1). The construct also features a HA protein tag on the C-terminus. Coiled coil A dimerizes with the coiled coil B, which was also described in Shekhawat et al.. If the B coil is fused to the N-terminal part of the split luciferase (BBa_K1965046), the luciferase can reassemble and regain its activity through the dimerization of the coiled coil pair A and B (2A) [1] .

We designed different destabilized coils from our coiled coil pair AP4 and P3; Ile and Leu were substituted with Ala at the a and/or d position of the first and/or second heptad of P3mS (a more soluble variant of the original P3).

HEK293T cells were transfected with plasmids, coding for the appropriate coiled coil constructs. 24 h after transfection cells were lysed and luciferase activity was determined with the dual luciferase assay. (A) A and B coiled-coils, fused the split firefly luciferase spontaneously interact and reconstitute firefly luciferase. (B) A’:TEVs:B:nLuc and cLuc:A:PPVs:B’2A auto-inhibitory coiled coils reconstitute activity of firefly luciferase upon cleavage by TEV and PPV proteases. Successive luciferase reconstitution is observed only at high amounts of plasmids coding for the A’:TEVs:B:nLuc and cLuc:A:PPVs:B’2A constructs.
