Part:BBa_K2235003
Cumate gene switch expressing BFP
This composite part is comprised of a complete inducible system, the cumate system. In particular, there is an expression cassette encoding the reporter gene, BBa_K592100 and there are two additional multiple cloning sites (MCS) flanking the reporter. The repressor of this expression cassette, CymR, is located upstream and it is constitutively expressed. The RNA spinach 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.
