iGEM Parts Registry. Homologous regions were modeled after those used in Elowitz, M. B., Levine, A. J., Siggia, E. D., & Swain, P. S. (2002). Stochastic gene expression in a single cell. Science, 297(5584), 1183-1186.
We created a modified backbone that will allow users to quickly and easily create parts that can be integrated onto the E. coli genome. This backbone is designed as follows (where H1 refers to the first region homologous to the E. coli genome, and H2 refers to the second homologous region) In order to insert a part onto the genome, the user simply needs to put a part onto this backbone (between the prefix and suffix), and PCR up the region between (and including) H1 and H2. Users can put their parts onto this backbone with their preferred method of assembly. This part exhibits resistance to chloramphenicol and kanamycin. The parts integrated with this cassette will contain kanamycin resistance, and will be integrated in the galK region of the E. coli genome. Homologous regions modeled after those in Elowitz et al 2002.

Temp part Suffix + H2 region GalK Temp WM used in designing K1795022, H2 region sequence inspired by Elowits et al 2002
Just the iGEM prefix, used to show components for part K1795202
Provides Kanamycin Resistance to the cell under the Promoter R0010.
GalK homologous region H2: Based off of Elowitz et al 2002, Used in construction of K1795023
Truncated pSB1C3 with no Prefix or Suffix
This part is a truncated version of pSB1C3 which does not contain a prefix or suffix. It is made to be used as a construction intermediate for the creation of new plasmid backbones which want to insert additional regions at either end of the backbone before replacing the prefix and suffix at either end of the backbone. It is used in K1795023.
We removed the prefix and suffix from pSB1C3 so we could add additional regions on either end of the backbone before replacing the prefix and suffix.
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.

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.
Double terminator consisting of BBa_B0010 and BBa_B0012
Forward KanR Protein Coding region only. Needs promoter, RBSs, and Terminator in order to provide Kan resistance.
Had to flip an existing parts direction to get this sequence
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.
