Supplementary Text 2 p.26 bottom paragraph:"lux system (Type II) - In the lux system, 3OC6-HSL induces luminescence at high cell densities by binding to the intracellular transcriptional regulator LuxR (Fuqua et al., 1996 Kaplan & Greenberg, 1985). Synthesis rate: The turnover rate of LuxI synthase (primary source Schaefer et al., 1996) is 1.1 mol of 3OC6-HSL min^-1 mol^-1 LuxI synthase, giving k = 3.3×10^3 nM/hr. Degradation rate constant: From the hydrolysis rate (primary source Kaufmann et al., 2005) of 3OC6-HSL da=3.07×10^-5s^-1 = 0.108 hr^-1." |
