For our project, four biobricks were submitted to the registry, all of which are added as basic parts. Although two of the parts contain multiple parts from the iGEM registry, these have not been entered as composite parts. The main reason for this is that the inclusion of biobrick assembly scars in certain parts of the toehold structure could mess with the structure and function of the toehold, and would impose additional constraints upon the toehold design. Given this, we believe that it would be most useful to the synthetic biology community if this was characterised was a basic part which can be swapped between plasmid vectors as required, and the target changed using Q5 site-directed mutagenesis.
The first part submitted is a synthetic toehold switch which has been placed under the control of a standard constitutive promoter (J23100) and modified into a biobrick, namely through the removal of a PstI site at position 844. Figure 1 shows annotated features for K1586000.
Part K1586000 has been characterised and shown to work as expected both experimentally and in silico. To see evidence of this, please visit the experiments page.
