pTAC cI-GFP

This part is used for the 2016 William and Mary iGEM Ribozyme Characterization project.

Choice of promoter influences the composition of the 5’ UTR on an RNA transcript. These 5’ UTR sequences can influence translation efficiency in a coding sequence-dependent manner. In 2012 Lou and Colleagues from the Voigt lab at MIT proposed a solution. By introducing the self-cleaving RNA ribozyme RiboJ immediately upstream of the RBS the authors were able to standardize the 5’ UTR of their transcripts.

We wanted to adapt this system to our Circuit Control Toolbox in order to insulate the input-output relationship (transfer function) of a circuit from its coding sequence. This allows our circuit modifications to be made independent of the original circuit architecture.

This part is a member of a set of test characterization devices to ensure that RiboJ insulation in the BioBrick standard insulates genetic circuitry. The part can be used in combination with BBa_K2066016 (constitutive Lac repressor) to investigate the transfer function.
