Part:BBa_K1840005
Device: TT-edd-mCherry
This device acts as a detector for glucose (and certain derivatives of it). The double transcription terminator ensures, that only the gene downstream of edd is influenced by the promotor edd. The edd promotor (BBa_K1840000) is contained in the genome of Pseudomonas putida and is situated in front of the enzyme edd (6-phosphogluconate dehydratase). The repressor HexR can bin the edd promotor sequence and thus prevent the transcription of the edd gene. In case the glucose derivative 2-Keto-3-deoxy-6-phosphogluconate is present, it binds the promotor and leads to a subsequent conformational change. Hence, the repressor can no longer bind and the gene downstream can be transcribed. In our device, the downstream gene is mCherry, codon optimized for Pseudomonas (BBa_K1840004). Therefore, in the presence of glucose, mCherry is expressed. In various experiments, we could see that this device is in deed working.
