Design Notes

As this part was taken from previously described research, our design decisions were mostly left to address the induction of the protein and termination of translation. We chose GAL1 as our promoter because we were unsure of the toxicity the construct might have in the cell. This way, we were able to grow the cells up in glucose media, which inhibits GAL1, until we had robust colonies and were comfortable expressing the novel construct. The specific terminator was chosen because the codon was optimized for S. cerevisiae. The entire sequence was optimized for S. cerevisiae using the IDT Codon Optimization tool.
