pBad mf-Lon
This is an arabinose-inducible mf-Lon construct containing the pBad promoter. William and Mary 2017 has modified the mf-Lon gene via codon-optimization for iGEM use and added a double terminator.
Usage and Biology
This part contains mf-Lon under the control of the inducible pBad promoter. The mf-Lon protease specifically targets different protein degradation tags with varying affinities 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
W&M 2017 characterized this mf-Lon containing part in combination with constitutively expressed reporter constructs as well as aTc-inducible pdt reporter constructs. The graphs below show this speed data for each of the 6 tags in the respective series (K2333407-K2333412 and K2333420-K2333426).
Time course measurements were performed according to standard protocol, and sfGFP fluorescence was normalized to steady state based upon when fluorescence no longer increased. As the no-Lon condition had not reached steady state when time course was ended, it was normalized to the final collected data point, which is likely close to the true steady state.
