Design Notes
We use the T7 promotor from Part:BBa_K525998(Group: iGEM11_Bielefeld-Germany (2011-09-13)) >sequence (32 bp) taatacgactcactatagggaaagaggagaaa We add additional sequence on it. There are two function in our sequence follow the T7 promotor. One is lac operator, the other is RBS binding site.
Lac operator could be bound with lac repressor. It could stop the transcription to prevent making protein. Genome of E.coli has the lacI gene. It could translate the repressor to inhibit protein produced. That is, we design the lac operator into our sequence to prevent the leak of expressing protein. RBS binding site could let the ribosome attach on the mRNA sequence to produce the enzyme. These sequence is derived from pET-29a(+) sequence. Because the original part has the restriction site”Xba1”in the sequence, and the sequence of this restriction site is” TCTAGA. “ We do the single mutation to convert TC”T”AGA to TC”C”AGA . Thus, the restriction site would not be recognized by restriction enzyme and cut off. That is, it is safe to use to compose the sequence for igem.
