Design Notes
The follow DNA sequence is the right DNA sequence of this part. After the giant jamborre we are able to replace the wrong sequence against this sequence.

As usual, a backbone is ligated with an insert to create the desired sequence. For example a new scaffold protein consisting of two domains can be constructed by ligating a backbone vector including the desired N-terminal scaffold domain with an insert containing the desired C-terminal domain. For this, the backbone has to be digested with the restriction enzymes BamHI and PstI cleaving the plasmid downstream of the first domain. In contrast, the insert has to be extracted from its vector by digestion with BglII and PstI. The overlap sequcences of the BglII and BamHI restriction sites are complementary. Thus, the insert can be ligated behind the first domain into the backbone. The scar sequence resulting from a combination of a BglII with BamHI restriction site cannot be recognized by nether of the enzymes. Therefore, a single ligation creates a new scaffold BioBrick immediately, which is again flanked by a BglII and BamHI sequence. Of course, more sophisticated scaffold BioBricks can therefore be constructed from composite BioBricks containing more than one domain or again by iterative cloning of single domains behind an initial domain.
Figure 2:
Cloning scheme for the construction of scaffold proteins. To assemble domains for the construction of a new scaffold protein, the backbone containing the N-terminal domain(s) can be digested with BamHI and PstI and the C-terminal domain(s) can be cut from the plasmid with BglII and PstI. The ligation of the two DNA fragments creates a new BioBrick, which can also be used for the construction of new scaffold proteins. Further scaffold proteins can be elongated by adding domains through the C-terminal BamHI site. The variability of the scaffold proteins can be increased by assembly of different domains. |
