Description Subparts
BBa_D0001 is a receiver device that can be used to sense the level of a cell-cell signaling molecule 3OC6HSL. A transcription factor, LuxR (BBa_C0062) that is active in the presence of 3OC6HSL is controlled by a TetR (BBa_C0040) regulated operator (BBa_R0040). Device input is 3OC6HSL. Device output is PoPS from a LuxR-regulated operator. This device is known to work in many E. coli strains at a range of temperatures and in a variety of media types.

Transfer Function

Figure 1 - Transfer function of BBa_D0001. The data points represent the mean of 6 or 9 individual measurements. The corresponding error bars represent the 95% confidence interval in the mean of the independent measurements. The blue shaded region represents the range bounded by the lowest and highest outputs among the independent measurements at a given input level. The solid black curve was calculated by fitting a simple Hill function to the experimental measurements.
