lacI:LVA device (constitutive promoter, RBS and terminator)
2013-09-16T11:00:00Z
2015-05-08T01:09:06Z
The source of the part will be its components.
The trancsriptional repressor lacI with LVA tag for faster degradation (BBa_C0012)under the constitutivly active promoter (BBa_J23106), with a RBS (BBa_B0030) and with a terminator (BBa_B1002).
This device can be used to overexpress lacI with the purpose of repressing transcription from high-copy plasmids containting the lac promoter (BBa_R0010). The repression can be relieved by allosteric binding of IPTG to lacI, thereby promoting transcription from the lac promoter.

false
Used a strong terminator so that the composite part can be used in front of the lac promoter without unwanted transcription of the regulated gene.

lacI-LVA
LacI-LVA (part C0012 without barcodes)
2013-09-16T11:00:00Z
2015-05-08T01:09:06Z
represillator of Elowitz and Leibler (2000)
See BBa_C0012
Coding region for the LacI protein with an LVA degradation tail and without an RBS. LacI binds to the pLac regulator BBa_R0010 and PLlac01 hybrid regulator BBa_R0011 and inhibits transcription. IPTG (Isopropylthiogalactoside) binds to LacI and inhibits its operation, therefore promoting transcription.
A rapid degradation tail (LVA) has been added to improve the switch time for High to Low performance of this part.

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.

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix ("orig" in figure 4-14 of Ron Weiss thesis). <p>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.
