Since, all the measurements were in terms of fluorescence, the V<sub>max</sub> for each Hill function was also in terms of fluorescence. In order to observe the effect of cross-talk we normalized the V<sub>max</sub> of non native interactions (in Lux system, P<sub>Lux</sub> being activated by LasAHL-LuxR, LasAHL-LasR or LuxAHL-LasR complexes) with the V<sub>max</sub> of the native interaction (LuxR binding to LuxAHL and activating P<sub>Lux</sub>). These ratios acted as weights for the effect of a non-native interaction on the promoter.

For an ideal whole cell model, it was necessary  to have no or minimum leakiness and cross-talk. However, in reality this was not the case. Although we were able to reduce leakiness significantly using riboregulators, we still had the issue of cross-talk. However,

For an ideal whole cell model, it was necessary  to have no or minimum leakiness and cross-talk. However, in reality this was not the case. Although we were able to reduce leakiness significantly using riboregulators, we still had the issue of cross-talk. However, we observe that the system shows XOR property till about 300 mins even with cross talk.
