Design Notes go hereThis composite part includes an Intein and linker, the TAL-effector Ax7L-DS, a TEV Site and a Strep Tag. They translated all together. The intein and linker are important to circularice the aminoacid sequence between the N- and C-terminal parts. Between the Intein sites is the TAL-effector and the TEV Site. There is also a strep II tag. When it is translated the intein sites react and form a circularised protein. All the parts between N- and C-Terminal Intein is part of the protein circle. In this circle the hole protein gains more stability.

Design Notes

This part synthesize a transcription activator like (TAL) effector protein. They were found in Xanthomonas bacteria. These bacteria are plant pathogenes and infects plants via a secretion typ III system. In the plant cells these proteins binds promoter sites. This leads to a transcriptional activation of the genes behind the promoter. The proteins contains tandem repeats up to 34.5. Each repeat binds one nucleotide of the target sequenz. The 12th and 13th amino acid of each repeat leads to the specific binding of the DNA sequence. We circularised the TAL-effectors with the help of Inteins at the N- and C- Terminus of each TAL-effector. The 12th and 13th amino acid of each of the repeats from our TAL effector Ax7R-RR are: NG NN NI NI NN NN HD NG NG NN NI NG NN NI NN HD NG They bind the DNA sequence: T G/A A A G/A G/A C T T G/A A T G/A A G/A C T
