Cumate gene switch expressing BFP
This composite part encodes all the necessary regulatory elements for a functional chemically inducible system, the cumate system. In particular, there is an expression cassette encoding the reporter gene, mTagBFP, BBa_K592100 and there are two additional multiple cloning sites (MCS) flanking the reporter (check the design page for more information). The repressor of the system, CymR BBa_K415202 , is located upstream of the expression cassette and it is constitutively expressed. The RNA spinach, BBa_K1330000, is an additional reporter protein following CymR aiming to detect its expression upon addition of its cognate fluorophore.
Usage and Biology
The cumate system have been previously described as a versatile and tightly regulated expression system induced by 4-isopropylbenzoic acid (cumate) in various strains of E.coli (1). It can be employed for the regulation and production of heterologous proteins in a dose-dependent manner. Moreover, the induction is achieved quickly within minutes therefore, a robust and homogenous expression of any protein can be achieved upon addition of cumate.
