5MT Inverter-GFP Reporter and Lac Promoter
Identical to part BBa_K223059 except with a Lac promoter. This part can be used to test the efficiency of the 5MT inverter system.
RBS (Elowitz 1999) -- defines RBS efficiency
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the 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.
The Plac insert was PCR'd from the MG1655 strain of E.coli K12.
Inverting regulatory region controlled by LacI (<bb_part>BBa_C0010</bb_part>, <bb_part>BBa_C0011</bb_part>, etc.) 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.
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.
Transcriptional terminator consisting of a 64 bp stem-loop.
green fluorescent protein derived from jellyfish Aequeora victoria wild-type GFP (SwissProt: P42212
GFP (mut3b) [note that this part does not have a barcode]
Originally taken from "Naturally occurring promoter down mutation: Nucleotide sequence of the trp promoter/operator/leader region of Shigella dysenteriae 16" (Miozzari,G and Yanfosky, C. Proc. Natl. Acad. Sct. USA. Vol. 75, No. 11, pp. 5580-5584, November 1978. Genetics). Sequence modifications done by Stanford iGEM 2009.
This is a modified trp operon, promoter and operator site, that recognizes and binds to a doubly mutant repressor sequence and its corepressor, 5-methyl-L-tryptophan. In conjunction with the mutant tryptophan repressor, this modified operon functions as an inverter, converting input 5-methyl tryptophan levels and converting decreasing levels of 5MT into a PoPs output signal for downstream transcription.
Point mutation from A to C on the second aporepressor binding site (i.e. -18) on the sense strand.
Original part taken from GenBank Escherichia coli IAI1: http://www.ncbi.nlm.nih.gov/nuccore/218552585?from=4690442&to=4690768& report=gbwithparts Two point mutation modifications made to change protein residue at 58 and 79 to Leu and Lys, respectively.
The 5 methyl-L-tryptophan aporepressor gene is a mutant version of the regular TrpR gene involved in sensing levels of synthetic compound, 5 MT. It works by binding to its corepressor, 5 MT, and then to its corresponding promoter operator, BBa_K223051, repressing downstream transcription. In the presence of low corepressor levels, the 5MT aporepressor will not bind allowing for downstream transcription.
