SnoopCatcher
The SnoopTag/Catcher system derives from a pilin of the bacterium Streptococcus pneumoniae. This system works similarly to the SpyTag/Catcher, also forming a covalent bond between a lysine and an asparagine and being constituted by short amino acid sequences. However, here the lysine can be found in the tag and the asparagine in the catcher.
Since both SnoopTag and SnoopCatcher are made of canonical amino acids, they can be linked to proteins of interest of different organisms. In addition, they bind to each other extremely specifically and the covalent bond is very stable under different pH and temperature conditions.
Via a small linker the SnoopCatcher can be added at the C- or N-terminal to any gene of interest.
In our project, we fused the SnoopCatcher to TnaA (BioBrick BBa_K4229011) for targeting to a microcompartment (wiffleball).
