Part:BBa_K3510003

Mn-Promoter-Mn-Riboswitch-FAST-Phytochelatine-Terminator

Important: This construct does not include a RBS upstream of the FAST2 sequence. When building on our design please make sure you add it in order to allow for translation

This composite part is a manganese inducible expression system of phytochelatin (BBa_K1321005) tagged with FAST2 (BBa_K3510000). Expression control consists of two individual elements: the manganese inducible promoter (BBa_K902073) and a manganese riboswitch (BBa_K902074). Transcription is regulated by the promoter, while the riboswitch supports translation initiation only in the presence of manganese. We combined both elements hoping for an even tighter regulation. Transcriptional termination occurs through the activity of the reliable double terminator (BBa_B0015).

Usage: In our project we coupled this manganese sensing device with a phytochelatin in order to create a bifunctional biosensor, that is not only able to detect manganese, but also directly binds it. With our suggested implementation this would contribute to the increase of water quality. The FAST2 tag allows a quantitative measurement of the fluorescence, which should provide information about the manganese concentration in the sample.
