Part:BBa_K157009

Split fluorophore linker; Freiburg standard

Originally, this linker was used for fusion to the N-terminus of the C-terminal half of split fluorophores: Protein interactions can be examined by BiFC[1] using complementary, non-fluorescent fragments of fluorophores[2]. Therefore, it is essential that the C-terminal fragment of the fluorophore is not restricted too much in its mobility. The linker allows orientation and adaption of the C-terminal fragment to the N-terminal fragment of the split fluorophore and, thus, the reassembly of a working fluorescent protein. It has already been used in BiFC assays and is known to serve this purpose well[3]; anyway, another, more flexible linker that could be used instead is our “GGGGS-linker” (Part Bba_K157010).
