From: An agmatine-inducible system for the expression of recombinant proteins in Enterococcus faecalis
Sensitivity of the aguR /P aguB expression system to the inducer. A. Induction strength of gfp in E. faecalis V583 cultures containing pAGEnt-GFP under induction with a range of agmatine concentrations. Cultures harbouring the empty vector pAGEnt, or the vector pAGEnt-GFP with no agmatine present, were carried in parallel as negative controls. Error bars: mean standard deviation of three independent experiments. B. Correlation between inducer concentration (mM) and reporter fluorescence (arbitrary units).
