Inverting regulatory region controlled by LacI (<bb_part>BBa_C0010</bb_part>, <bb_part>BBa_C0011</bb_part>, etc.) <p> The pLac regulatory region is a 243 base-pair sequence with standard BioBrick prefix and suffix sections on its ends. It contains two protein binding sites: CAP, which is generally present in E.coli and is assocciated with cell health and availability of glucose., and LacI, the Lac inhibitor <bb_part>BBa_C0010</bb_part> which binds in an dimerized cooperative manner to inhibit the transcription of the protein that follows. In the presence of lactose or IPTG, an analog of lactose, LacI is unable to correctly bind and inhibit transcription. This allows <bb_part>BBa_R0010</bb_part> to be used as a inverter or as a detector of lactose or IPTG.

<P> <P><P> LacI binds to this regulator. This part is incompatible with species containing active LacI coding regions. Lactose and IPTG disable the operation of LacI and this regulator. This part is incompatible with environments containing lactose or lactose analogs.

[key3c] riboregulator for lock3 variants

J23007
This part has the same homology region to J01122 as J23007 except that unlike J23007, J23008 does not contain the hairpin that was derived from J01129. J23008 anneals linearly to the stem of the hairpin in J01122 with perfect base pairing and destroys the hairpin in the process and reveals the RBS on J01122. When J01122 is transcribed the RNA secondary structure is such that the RBS hairpins with sequence upstream preventing the ribosome from binding and translation from occuring thereby locking up RFP further down stream. When J23008 is introduced into the cell in trans, we suspect that it will unlock the RBS for RFP as described above allowing translation to occur.
