A part used to quantify the AraC-RBS construct <partinfo>K259007</partinfo> created by the BCCS-Bristol iGEM'09 team.
This part was designed with the specified biobricks from the parts registry. AraC occurs naturally in E.coli. GFP occurs in jellyfish species, RBS designed by the Anderson family and Terminator by Resma Shetty.
This part has the arabinose regulated promoter (AraC/pBAD) upstream of a ribosome binding site. This is ideal for inserting a protein to be expressed downstream of this part as it's expression can be regulated by the presence of the concentration of arabinose in the growing environment/media of the cells. ==What this part actually does== This composite part includes the AraC/pBAD promoter and a strong ribosome binding site designed from the Anderson family of RBS. The AraC/pBAD promoter can be used with prokaryotic chassis to regulate expresion of proteins. When the AraC/pBAD promoter is placed upstream of your canditate translational unit (protein to be expressed) it allows control of the trancription of the said protein. This is done via controlling the concentration of arabinose sugar in the environment/solution of bacterial growth. Controlling the transcription will not ensure translation. The ribosome binding site is ideally placed a small distance away from the promoter site to ensure that the ribosome will bind and start translating the protein coding sequence found downstream.
The part was designed with RFC10 assembly from supplied biobricks of the iGEM2009 distribution.
The AraC promoter can be found naturally at 1.52min of the E.coli genome ([http://ecogene.org/geneinfo.php?eg_id=EG10054 EcoGene number EG10054]. The RBS was taken from the designed sequences of RBS by the Anderson family. For more information visit the original part page [http://partsregistry.org/Part:BBa_J61100 here].
green fluorescent protein derived from jellyfish Aequeora victoria wild-type GFP (SwissProt: P42212
GFP (mut3b) [note that this part does not have a barcode]
Inhibitor (AraC loop attachment with O2 site)
this piece of DNA contains a "dead" part of coding region for AraC, and a functional Operator2 site. when attached to the rest of the promoter region, this part allows for the binding and loop formation that would result in repression of the araC promoter
1) changed ATG start codon to TAG stop 2) 6 random deletions upstream of putative araC binding sites to preserve spacing for loop back (BB ends will add 6 base pairs); spacing crucial in matching up O2 and I2 binding sites (turns of DNA helix) 3) designed to attach to R0080 to enable all (positive and negative) regulatory functions, and to form "loop back"
Derived from luxICDABEG operon terminator of Vibrio fischeri <genbank>AF170104</genbank>.
Bidirectional transcriptional terminator consisting of a 22 bp stem-loop.
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.
AraC operator, truncated to include araO1, araI1, araI2, c-amp1, and c-amp2 sites. This operator should *activate* transcription in the presence of AraC; b/c the operator lacks the araO2 site, there should not be araC-mediated repression.
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.
