Promoter (lacI regulated, lambda pL hybrid)
represillator of Elowitz and Leibler (2000)
Inverting regulatory region controlled by LacI (<bb_part>BBa_C0010</bb_part>, <bb_part>BBa_C0011</bb_part>, etc.) The PLlac 0-1 promoter is a hybrid regulatory region consisting of the promoter P(L) of phage lambda with the cI binding sites replaced with lacO1. The hybrid design allows for strong promotion that can nevertheless be tightly repressed by LacI, the Lac inhibitor (i.e. repressor) (<bb_part>BBa_C0010</bb_part>) ([LUTZ97]). The activity of the promoter can be regulated over a >600-fold range by IPTG in E.Coli DH5-alpha-Z1 (same paper reference).
hybrid promoter design to create strong promoter that is, at the same time, highly repressible. note that the upstream operator installed in this hybrid is slightly different than the one in the original source (Lutz and Bujard, 1997). the most upstream operator region is slightly truncated in the represillator version, so that both operators in the hybrid are the same sequence. see references for details. also, the sequence has been truncated after the transcriptional start site. 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 increase transcription. This part is incompatible with environments containing lactose or lactose analogs.

Promoter that can be induced by phosphate.
Promoter that can be induced by phosphate. The downstream promoter has a single copy of the pho box, the consensus sequence shared by the pho promoters. These pho boxes are the binding sites of its corresponding response regulators phoB. Two molecules of phoB protein form a complex that could bind to the pho boxes and up-regulate the downstream expression.
RBS.3 (medium) -- derivative of BBa_0030
Weak1 RBS based on Ron Weiss thesis. Strength is considered relative to <bb_part>BBa_B0030</bb_part>, <bb_part>BBa_B0031</bb_part>, <bb_part>BBa_B0033</bb_part>.
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix ("RBS-2" in figure 4-14 of thesis). Contact info for this part: Brian Chow

mCherry, bacterial with RBS and forward terminator
Combines BBa_B0015 forward terminator with BBa_J06602 mCherry, bacterial with RBS
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.
Transcriptional terminator consisting of a 64 bp stem-loop.
Coding region for the LacI protein with an LVA degradation tail and without an RBS. LacI binds to the pLac regulator <bb_part>BBa_R0010</bb_part> and PLlac01 hybrid regulator <bb_part>BBa_R0011</bb_part> and inhibits transcription. IPTG (Isopropylthiogalactoside) binds to LacI and inhibits its operation, therefore promoting transcription. A rapid degredation tail (LVA) has been added to improve the High to Low performance of this part.

[ELOW00] References (unparsed) here: Elowitz, M.B., Leibler, S. A synthetic oscillatory network of transcriptional regulators. Nature 403, 335-338 (2000). [ELOW00] Sequence taken from the repressilator of Elowitz and Leibler (2000). The obtained sequence was compared to the wild-type sequence for LacI obtained through a database search. The sequence had been modified from the wild-type in that wild-type GTG start was changed to an ATG start (note, actual ORF in E.coli has several GTG starts it would seem). The LVA tag has been added for quicker degradation. Incompatible with systems containing LacI, lactose, or IPTG.

mCherry from Roger Y. Tsien's lab, altered to be BioBrick compatible
mRFP (DsRed) derived, altered to be a biobrick by removing a PstI site and adding in the ends.
Made a point mutation to eliminate a PstI site in the middle and then added BioBrick ends using PCR. Sequenced using primers that bind to the pSB1A2 plasmid on either side of the brick.
This is a PPK Coding Sequence which can remove phosphate from water
This is a PPK CDS which is created by Jack Jia from Shenzhen_SFLS and with Eric's great help. The polyphosphatase then degrades phosphates present when there is too much phosphorus in water. We use it as a CDS in our project.
Nothing. Everything goes on well during our research.
This part is a main part in the genetic circuit. With a ppk, RBS and a promoter it can be a whole genetic circuit. Can be used for dissolving phosphorus in water.
We think that it can be very useful in the whole genetic circuit. During the research everything goes fine.
