Unfortunately the model parameters (k<sub>cat</sub>, k<sub>M,AiiA</sub>) were not estimated because placing the device in low copy plasmid (<a href="https://parts.igem.org/Part:pSB4C5">pSB4C5</a>)resulted in no HSL degradation, as shown in the figures below:

NB: unless differently specified, all tests were performed in E. coli MGZ1 in M9 supplemented medium at 37°C in low copy plasmid pSB4C5.

The AiiA enzyme activity has been characterized under the regulation of ptet promoter, assaying its enzymatic activity, with these parts:


A system of differential equations has been derived and parameters would have been identified, studying the exponential growth phase:
The four measurment parts ptet-RBSx-LuxI were quantitatively characetrized using the BBa_T9002 biosensor. Unfortunately the model parameters (kcat, kM,AiiA) were not estimated because placing the device in low copy plasmid (pSB4C5)resulted in no HSL degradation, as shown in the figures below:
A semi-quantitative information about AiiA enzyme activity is given, performing an experiment in E. coli TOP10, with the four measurement devices in pSB1A2; the results are summerized in the graphs below:
In this way a measure of AiiA activity is given, as the percentage of HSL degraded in 7 hours (measurements provided as average [stdandard deviation]):
Measurement device HSL degraded percentage
BBa_K516220 96.11 [3.66]
BBa_K516221 77.60 [2.66]
BBa_K516222 50.66 [16.87]
BBa_K516224 100 [0]

In order to evaluate the RBSs efficiency, the ratio between the percentage of the degraded HSL realtive to the measurement device with the standard RBS (BBa_B0034) was computed:
RBS RBS efficiency
BBa_B0030 0.96
BBa_B0031 0.78
BBa_B0032 0.51
BBa_B0034 1
