mTurquoise2 with C-terminal SnoopCatcher regulated by tetA/B promotor

This composite BioBrick was used to visualize protein targeting into microcompartments by fluorescent microscopy. The SnoopCatcher is fused to the C-term of mTurquoise2.

We used this fusion protein to test the functionality of our compartments: the minimal wiffleball (BBa_K4229047), full wiffleball (BBa_K4229049), and SPD-5 (BBa_K4229078). All compartmentalization proteins have an N-terminal SpyTag.

A fluorescent signal in the bacteria that expressed either protein could be detected. Upon co-expression with compartmentalization proteins, foci were formed (especially well with the full wiffleball) with both reporter genes:

We could show that mTurquoise2 is targeted to microcompartments when coexpressed with full or wiffleball.

:Western Blot showing the formation of the peptide bond between the T1 protein and mTurquoise2 in cells expressing the full and the minimal wiffleball with and w/o tags. The detection of the T1 protein was performed with an anti-his antibody.















With that, we can say that our mTurquiose2 with the snoopCatcher is successfully expressed and caught by our compartment.
