10 aa linker with BamHI restriction site and TEV recognition site

Design Notes

Standard assembly [RFC10] with this part creates scarsite (uacuag). Scarsites encodes stopcodons, which is inconvenient for the right use of this linker. The linker instead contains a 5'-end BamHI restriction site to be used in fusion to proteins with a 3'-end BamHI restriction site. For implementation, we recommend the following assembly method:

1) Design primers for amplification of the C-terminal fusion protein with the DNA sequence for the linker in the overhang of the forward primer. 1.2) Forward primer: 5'-CGCTTCTAGAGGGATCCGAAAATTTGTATTTTCAATCTGGTNNN...NNN-3' - (XbaI res. site and linker(with BamHI res. site) included) 1.3) Reverse primer: 5'-ATATCTGCAGCGGCCGCTACTAGTANNN...NNN-3' (SpeI and PstI res. site included) 2) Run PCR with designed primers. 3) Digest PCR-products and a standard backbone (e.g. pSB1C3) with XbaI and PstI 4) Ligate backbone and PCR product

Addition of linker_C-terminalFusionProtein to N-terminal fusion protein: 5) Design primers for amplification of N-terminal domain that includes a 3'-end BamHI res. site. 5.1) Forward: 5'-CGCTTCTAGAGNNN...NNN-3' (includes XbaI res. site) 5.2) Reverse: 5'-ATATGGATCCNNN...NNN-3' (includes BamHI res. site) 6) Run PCR with designed primers. 7) Digest PCR-products and plasmid containing linker_C-terminalFusionProtein with BamHI and PstI(or SpeI) res. site. 8) Ligate backbone PCR product
