This construct is a control to test the metabolic load of the Hsp104-CFP fusion protein and as a baseline against which we compare the change in [PSI+]/[psi-] state. We synthesized a fragment to clone into the [Hsp-PRS315]. This plasmid will be referred to as the Hsp104 plasmid and is used in several of our experiments.
CFP was synthesized with a stop codon in the place of Tyr-39 (TAC -> TAG) and amplified with flanking ApaI and BamHI sites. The premature stop codon (before the CFP fluorophore) was expected to truncate the protein during normal transcription. Fluorimetry readings were then used to quantify the amount of read-through for the CFP-tagged Hsp104.

This biobrick contains a fusion of the ADH1 promoter and GFP. ADH1 is a eukaryotic promoter; the presence of ethanol induces it. The fusion between it and GFP allows the strength of the promoter to be quantized in varying concentrations of ethanol using the fluorescence of the GFP.
This biobrick is a fusion of the Gal1 promoter and GFP protein. Gal1 is a eukaryotic promoter; the presence of galactose induces it. The fusion allows the strength of the promoter to be quantized in the presence of varying concentrations of galactose using the fluorescence of the GFP.
This biobrick is a fusion of the Cup1 promoter and GFP protein. Cup1 is a eukaryotic promoter; the presence of Cu2+ induces it. The fusion allows the strength of the promoter to be quantized in the presence of varying concentrations of copper ions using the fluorescence of the GFP.
This biobrick is a fusion of the Gal1,10 promoter, Cyan Fluorescent Protein (CFP), and the chaperone protein Hsp104.
