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.</P> <P>A rapid degredation tail (LVA) has been added to improve the High to Low performance of this part.</P>

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <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.

Inverting regulatory region controlled by LacI (<bb_part>BBa_C0010</bb_part>, <bb_part>BBa_C0011</bb_part>, etc.) <p> 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).

<P> <P>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.<P>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.

<P> <P>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.<P>
