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 we used Potassium Laurate 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.

Our results suggest that the recombinant strain ''E. coli'' 029A functionally express our biobrick [http://partsregistry.org/Part:BBa_K398029 BBa_K398029]. From the statistical analysis that we performed we concluded that the expression of the biobrick [http://partsregistry.org/Part:BBa_K398006 BBa_K398006] under the promoter-rbs combination [http://partsregistry.org/Part:BBa_J13002 BBa_J23100]-[http://partsregistry.org/Part:BBa_J13002 BBa_J61117] increases the dodecanal dehydrogenase activity in ''E. coli'' cell extracts 2-fold. Moreover, the enzymatic activities measured for the construct [http://partsregistry.org/Part:BBa_K398029 BBa_K398029] were equivalent to 33.98% of the ''Pseudomonas putida'' aldehyde dehydrogenase activity.

pCaiF a natural promoter in E. coli that is active at high cAMP levels was characterized attaching E00240 in front of our part. Different GFP production rates were found at the stationary phase showing that GFP production depends on the amount of glucose in the medium. Moreover, growth on a secondary carbon source decreases the GFP production rate.

The solvent tolerance cluster (BBa_K398406) was expressed on in ''E. coli'' K12. The growth of the cells was tested under different amounts of n-hexane. The results show that this part gives to the cells an growth advantage at higher n-hexane concentrations. The parental strain E. coli K12 grows really slow at 10% (v/v) of n-hexane/M9 mixture.

Our results suggest that the recombinant strain E. coli 029A functionally express our biobrick [http://partsregistry.org/Part:BBa_K398029 BBa_K398029]. From the statistical analysis that we performed we concluded that the expression of the biobrick [http://partsregistry.org/Part:BBa_K398006 BBa_K398006] under the promoter-rbs combination [http://partsregistry.org/Part:BBa_J13002 BBa_J23100]-[http://partsregistry.org/Part:BBa_J13002 BBa_J61117] increases the dodecanal dehydrogenase activity in E. coli cell extracts 2-fold.

According to our results, the smallest part that we designed it's working!!!

pCaiF a natural promoter in E. coli that is active at high cAMP levels was characterized attaching E00240 in front of our part. Different GFP production rates were found at the stationary phase showing that GFP production depends on the amount of glucose in the medium. Moreover, growth on a secondary carbon source decreases the GFP production rate.
