Part:BBa_K831017

PxpsR-EYFP

Fluorescence reporter that responds to the presence of 3OH-PAME (Quorum Sensing signal).

Promoter region of xpsR (PxpsR) wich integrates different signals including phcA. Expression of genes regulated by XpsR may be correlated with threshold concentrations of 3 OH-PAME.

Functional Characterization

To assess the fuctionality of our part Escherichia coli K12 DH5a were transformed with part BBa_K831017

Bacterial strains were photographed while using Differential Interference Contrast (DIC) microscopy and Fluorescence microscopy using FITC filter. Bacteria transformed with PxpsR-eYFP construct show basal levels of expression of the reporter while none of the bacteria transformed with the promotorless EYFP show fluorescence. High background levels in the promotorless EYFP are due to the autoflorescence of the LB medium and the high exposition time.
