pBad mf-Lon
This is an arabinose-inducible E. coli optimized mf-Lon construct. Arabinose inducibility is provided by BBa_I0500, William and Mary 2017 iGEM found early on that this part had leaky expression, and thus did not perform any high-quality characterization of this part.
Usage and Biology
This part contains mf-Lon under the control of the inducible pBad promoter. The mf-Lon protease specifically targets protein degradation tags (pdts) with various corresponding to varying degradation rates. This arabinose-inducible mf-Lon construct was used in tandem with aTc-inducible pdt reporter constructs to obtain gene expression speed measurements.
Characterization
A concentration of 0.1mM arabinose was sufficient to create degradation of mScarlet-I and sfGFP [http://2017.igem.org/Team:William_and_Mary/Parts parts], 1mM arabinose increased degradation but lead to high amounts of cell death. 0.01mM Arabinose generally increased expression.
