BBa_K2176001
Cassette for the constitutive production of GAL4-KaiCp and LexA-SasA, linked by a self-cleaving P2A

The promoter and terminator in this cassette were amplified from the yeast genome, using primers that added extra overhangs with novel restriction enzyme cut sites on either end: the BioBrick prefix (for the promoter) or suffix (for the terminator) on one side, and an overhang with a cut site for ligating the part to the protein coding sequence on the other side. The protein coding domain was synthesized in G-blocks and constructed via Gibson assembly.
None of these components came from their own BioBricks, which is why we've entered the composite as a single "Basic" part.
This part is a composite of four parts:
1) a (constitutive) yeast TEF1 promoter
2) a protein coding sequence for a fusion of the GAL4 activator domain and phosphorylated KaiC
3) a protein coding sequence for a fusion of LexA and SasA
4) and a yeast ADH1 terminator
The two protein coding sequences are linked by a P2A linker domain, which is self-cleaving.
This part works in tandem with a GFP reporter construct we designed (BBa_K2176000) that is regulated by a LexA operator. The LexA protein from this part (that is, BBa_K2176001) binds to the LexA operator, carrying with it the SasA protein to which it is fused. SasA binds phosphorylated KaiC (KaiCp), which is made by this cassette in a 1:1 ratio with the LexA-SasA fusion. This KaiCp is fused with a GAL4 activator domain, which recruits RNA polymerase. As a result, an organism expressing both this cassette and the GFP reporter BBa_K2176000 will be constitutively expressing GFP.

We chose to express both fusion proteins in one cassette, joined by a self-cleaving linker, in order to obtain equal stoichiometric amounts in the cell.
In order to join the promoter and terminator to the protein coding sequence, we used two restriction enzymes, BamHI and BglII, which produce the same sticky ends when cut but have different recognition sites due to differences in the base pairs flanking the sticky ends. The promoter was cut with BamHI, while the side of the protein coding sequence it was to be joined to was cut with BglII. These two were then able to ligate together, which produced a novel 6bp sequence that is half-BamHI site, half-BglII site, and as a result is a recognizable cut site to neither. The same procedure was used to join the protein coding sequence and the terminator.
