represillator of Elowitz and Leibler (2000)
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] 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.

Double terminator consisting of BBa_B0010 and BBa_B0012
The RBS (BBa_B0034) was combined with cinr (BBa_C0077), cinl (BBa_C0076) and D-term (BBa_B0014) to create a single transcription control device for BBa_R0078
Comparing to BBa_I761000, double terminator is added in the end of this construct

Constitutive promoter (strong) with RBS (strong, efficiency=0.3)
This is a regulated promoter that regulated by LacR and AHL.
This is a Constitutive promoter that product araC protein, it will reduce the pBAD expression, unless the arabinose has been added.
We can use this part to make a gene sequence to produce some protein regulated by arabinose.
The sequence was obtained by applying all mutations that upregulated AraC binding and subsequent promoter activity listed in reference [1].
pBAD is an E.coli promoter that is induced by L-arabinose. K206000 is a mutagenized pBAD promoter that is responsive to lower concentrations of arabinose than wild type (<partinfo>I13453</partinfo>) and, additionally, exhibits a higher maximum of protein expression as measured by coupling to a fluorescent reporter.
There were no special design considerations.
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.
RBS.1 (strong) -- modified from R. Weiss
Strong RBS based on Ron Weiss thesis. Strength is considered relative to <bb_part>BBa_B0031</bb_part>, <bb_part>BBa_B0032</bb_part>, <bb_part>BBa_B0033</bb_part>.
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix ("orig" in figure 4-14 of Ron Weiss thesis). 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.

Double terminator consisting of BBa_B0012 and BBa_B0011
This part is intended to be used as an transcription activator for BBa_R0078. It can be used to control the expression of the gene downstream of BBa_R0078.
The RBS (BBa_B0034) was combined with CinR (BBa_C0077) and HSL (BBa_C0076) to create a single transcription control device for BBa_R0078.
Lac repressible 3OC6HSL generator (No LVA)
Generates an untagged LuxI enzyme which produces an AHL(3OC6HSL) under a lac-repressible promoter.

PC and AraC from the AraBAD operator. PC and AraC are on the complementary strand, reading right to left.
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.

Bidirectional transcriptional terminator consisting of a 22 bp stem-loop.
In the naturally-occuring sequence there is a mismatch in the stem of the stem loop. This can be corrected via an A->G mutation (at position 40 -- sequence coordinate/not MFOLD coordinate). The above sequence does not reflect this mutation (but the MFOLD image does). This terminator's location cannot be found using some inverted repeat detectors like PALINDROME because it is too short and contains a mismatch. This one was found with the help of Tom Knight. It lies between two coding regions that point towards eachother.
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.
cinI codes for an autoinducer synthetase which utilizes SAM to make O3-C14:1-HSL. In complex with O3-C14:1-HSL, CinR (BBa_C0077) binds to the Cin promoter (BBa_R0077) and activates transcription.
