Sensing Results

pCaiF strength

BBa_K398326

pCaiF is one of our Biobricks of the sensing project. It's function is to express proteins under glucose limitation conditions. In order to measure its strength we attached the GFP generator in front of it. Different media, and carbon source concentrations were tested in order to obtain an insight about the protein production during starvation.

Also, it is well known that this promotor it's active during diauxic shifts, that's why we measured the GFP production using glucose as a first carbon source (concentration of 1g/L) and Potassium Laurate (5mM) as a secondary carbon source. The results that we got suggest that the part works like a charm! During glucose starvation high levels of cAMP can be found in cells, which enhances the expression of the proteins downstream of this promoter. On the other hand when the secondary carbon source is being catabolized by the cells, cAMP levels drop and thus the expression of genes regulated by pCaiF.
