PR1 promoter is an attenuated promoter of the pBEST plasmid’s PR promoter. It can be used in a polycistronic plasmid to express more than one gene. It can be used to get lower expression levels of genes than the original PR promoter, which can sometimes help the protein expression and was shown to be more effective during in-vivo gene expression. Our devices contain this promoter, alongside Bti toxin subunits and deGFP, thus expressing toxins with functional usage and deGFP for tracking of our bacteria.

Usage and Biology Promoters are regulatory DNA parts, which can be used to express genes.

Characterization The PR1 promoter can be expressed in E. Coli and Serratia Marcescens. In the following photos, we see genes expressed from the polycistronic plasmid, which our PR1 promoter is it’s promoter in Serratia Marcescens 274 fed to Aedes Aegypti mosquitoes larvae.
