small molecule controlled, riboregulator based XOR gate
The Collins lab riboregulators and existing registry parts.
This device uses the small molecules lac and tet as inputs and expresses GFP as an XOR function of the two.
The presence of either (but not both) of the keys unlocks a blocked RBS to allow translation of a CFP degradation tag fusion. The two keys have a greater affinity to each other than to the lock, so the presence of both does not unlock the blocked RBS.
Derived from the TE terminator of T7 bacteriophage between Genes 1.3 and 1.4 <genbank>V01146</genbank>.
Transcription terminator for the E.coli RNA polymerase.
Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG). Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
Transcriptional terminator consisting of a 64 bp stem-loop.

Sequence for pTet inverting regulator driven by the TetR protein.
BBa_R0040 TetR-Regulated Promoter is based on a cI promoter. It has been modified to include two TetR binding sites and the BioBrick standard assembly head and tail restriction sites.

enhanced cyan fluorescent protein derived from A. victoria GFP
Modified from <bb_part>BBa_E0021</bb_part>.
Cyan fluorescent protein (ECFP) reporter coding sequence without the Ribosome Binding Site. Modified with an LVA tail for rapid degradation of the protein and faster fall time for the emission.
BBa_E0022 cyan fluorescent protein is based on BioBrick part BBa_E0021. It has been modified to include a rapid degradation LVA tail, and includes the BioBrick standard assembly head and tail restriction sites. The RBS has been removed. The stop codon has been changed from TAA to a double stop codon TAATAA.
