Introduction

P_fus(4 Ste12 binding sites)

General

The original Pfus (BBa_K1154001) is 201bp long with three STE12 binding sites, and the STE12 is Pfus’s transcriptional activator in the endogenous GPCR pathways of yeast.

fig.1 The sequence of original Pfus

In order to enhance the transcription initiation activity of the promoter, we add additional one binding site(gatgaaacaa) in the front of the promoter.

And we add 5umol/L α pheromone to detect the modified promoter, and the result is shown in fig.2.
