pDualPH1-pDual mcherry-yeGFP High 1

Description

The functional promoter sequence (about 223 bp) generated by our AI model Pymaker is inserted into the dual-fluorescence reporter system for characterization and we describe it as pDualPH1. Random DNA yields diverse expression levels in a yeast promoter library, while we can use the episomal dual reporter system expressing a constitutive red fluorescent protein (RFP) and a variable yellow fluorescent protein (YFP) to quantify promoter activity. By adpoting the log(YFP/RFP) measured using flow cytometry, we can detect the expression rate of our synthesized promoters. The advantage of this system is its ability to eliminate the influence of plasmid copy number and the growth status of the bacterial host, thereby providing a more direct measurement of the relative expression strength of the synthesized promoters by the Pymaker.

Loci

pDualPH1 consists two parts: the synthesized core promoter and the pDual reporter scaffold. The synthesized core promoter is an 80 bp sequence generated by the Pymaker and is seated at approximately -170 to -90 upstream to the codon (which is the presumed transcription start site-TSS and is where most transcription factors binding sites lie). The he pDual reporter scaffold can link the core promoter with the codon and provide restriction sites of BamH I and Xho I which make it possible for the plasmids with the scaffold to be inserted by various core promoter sequences at ease.
