LasR Autoinducing Loops
Our second memory unit consists of a LasR gene(Bba_C0179) driven the LasB promoter(Bba_R0079). LasR only activates transcription in the presence of HSL, this was added to the medium in a concentration of 100nM.
Leakage of the LasR autoinducing loops
To estimate the autoactivation of the LasR loop through a leaky promoter we measured fluorescence of cells carrying the following constructs:
