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.

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.

kanamycin resistance forward (KanF) [cf. BBa_J23012 & BBa_J31002]
If there is a promoter and an RBS before this region, the cell will express Kanamycin resistance. As it has full biobricks, you can easily add KanR to an existing part without changing the plasmid vector,
Built by Josh as an intermediate in screening plasmid construction.
**highly** engineered mutant of red fluorescent protein from Discosoma striata (coral)
Campbell et al., PNAS v99 p7877 URL
monomeric RFP: Red Fluorescent Protein. Excitation peak: 584 nm Emission peak: 607 nm
TAATAA double stop codon added (DE). Four silent mutations made to remove three EcoRI sites and one PstI site: A28G, A76G, A349G, G337A.
tetracycline resistance protein TetA(C) (forward), [cf. BBa_J31006]
This part is the coding region of the TetR gene. It requires a promoter and RBS for the cell to be able to express tetracyline resistance.
