His-Dig-Split Linker-Fok_a

This combination uses the benefits of a His tag (Polyhistidin tag) for purification. It is also linked with a DigoxigeninA tag (DigA). The Split Linker connects the parts and adds additional space between them to guarantee the independent function of DigA tag and the protein domain Fok_a.


Usage and Biology

This composite part is one part of our universal endonuclease and it needs another composite part like BBa_K243010 to build a functional heterodimer. The DigA tag guides the part to the DNA which is hybridized with a Digoxigenin labeled oligonucleotide. The Split Linker creates a distance of 51bp between the DigA and the linked Fok_a protein domain. The His Tag serves as a purification tag for Ni-NTA column purification.

We applied the His tag to enable a simultaneous purification of constructs with a Strep tag. The used DigoxigeninA tag allows coupling to a Fluorescein linked oligo. Emanating from our 3D modeling this combination of DigA tagged oligos and the construct containing the protein domain Fok_a is more efficient than the use of a combination of FluA tagged oligos with a construct containing Fok_a. To avoid interactions between the DigA tag with the connected protein domain Fok_a, we applied the Split Linker. The linker itself has no influence on the connected parts. We decided to use the Split Linker for this construct to get a longer distance between DigA tag and Fok_a to guarantee the independent function of both parts. This linker is an improved part of the team Freiburg08 and it is suitable for fusion proteins. The properties of the Split Linker are a good compromise between the stability and the distance of the connection between protein domain Fok_a and the anticalin tag.
