This composite part includes an Intein and linker, an eGFP, a TAL-effector, 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 an eGFP and the TAL-effector in frame. There is also a strep XT tag and the TEV Site. 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.

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.

With the help of the strep XT tag the protein can be purified even if it is circularised. The Strep XT Tag is also usefull to detect the protein with an immunostain. The TEV Site give the opportunity to linearise the protein again wit the help oft he TEV protease. The linearised TAL can bind the specific DNA Sequence. The eGFP gives us the opportunity to detect the connected TAL-effector. The TAL effector is the Hax3-2xNG.

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 11.5 repeats from our TAL Hax3 – 2xNG (B) are: NI HD NI HD HD HD NG NG NS HD NI NG. They bind the DNA sequence: A C A C C C T T N C A T
