light receptor is made of I15008,I15009,I15010,and R0082. LacI is C0012.
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.

Positively regulated, OmpR-controlled promoter. This promoter is taken from the upstream region of ompC. Phosphorylated OmpR binds to the three operator sites and activates transcription.
The promoter includes the three OmpR binding sites: C1, C2, and C3. The promoter starts at -107 and goes up to the transcriptional start site at +1. An alternate version, BBa_R0083, cuts out the C2 and C3 sites. The efficacy of this promoter versus the truncated ompC upstream region (BBa_R0083) or the ompF upstream region (BBa_R0084) is currently unknown.

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] 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.
